Oh it's probably galacticraft. Thanks dude!
You play with galacticraft and gregtech? Then I'm curious what versions of forge, galacticraft and gregtech do you use. I'm asking because I had hard-to-reproduce bug with getting oxygen to blast furnace's input hatch.
I was a bit bored at work, so calculated the cost to produce one neutronium ingot with the fusion reactor assuming no naquadah ore found:
16 Chrome
1344 Thorium
1280 Plutonium
7h36min fusion runtime
44,225,599,488EU
1280 Plutonium would require 6 * 9 * 400 * 1280 = 27648000 (or ~422 full chunks) red granite.
Having encountered Thaumcraft taint, I dream about "nuclear powered taint remover". Could you add something like that?
I would like to use "industry" to clean up magical mess. Currently Thaumcraft adds only weak tools against taint, which at the same time are too boolean.
I'm pretty sure the fluid hashmap is broken due to changed fluids over time on a old server after many updates.
Server was very recently restarted (updated to gregtech 5.08.16).
Can you take a quick look if the problem also happens in Singleplayer? If not i'm sure i know why it happens and it will be difficult to test...
On singleplayer it works (accepts oxygen). But this time I used single MV energy hatch. On multiplayer I used 3 LV energy hatches. Might be related.
Why do you use Galacticraft Oxygen anyways? That is not really meant to work anyways. With GT Oxygen everthing works, so there is no bug...
If you absolutly want GC Oxygen to work, i will add a recipe balanced to its production costs.
I don't use galacticraft oxygen. I only said that I have galacticraft installed.
What would help me is a config option to disable a check mRecipeMap.containsInput(aFluid) for input hatch. But that would be a workaround, not a fix. Very likely that no machine accepts oxygen at my setup.
I did some research why input hatch doesn't accept oxygen.
Mod versions: forge 1408, gregtech 5.08.16, galacticraft build 333. I mentioned galacticraft because it adds oxygen gas.
Setup: Input hatch belongs to an electric blast furnace. There is an oxygen source (electrolyzer or pipe) attached to input hatch's front facing.
Symptoms: While playing, input hatch does not accept oxygen. On chunk load (reconnecting to server, switching dimension and back) 5000 to 7000 liters of oxygen move from oxygen source to input hatch. Always. That oxygen I use to smelt steel (from wrought iron). So I can work around this bug by reconnecting many times.
Why:
gregtech.api.metatileentity.implementations.GT_MetaTileEntity_Hatch_Input :
line 15: public GT_Recipe_Map mRecipeMap = null;
it is initially null, and is set to recipe map at some point in the future.
public boolean isFluidInputAllowed(FluidStack aFluid) {
return mRecipeMap == null || mRecipeMap.containsInput(aFluid);
}
mRecipeMap.containsInput looking deeper is just a check if a hash contains key, where key is net.minecraftforge.fluids.Fluid (quite complex class).
gregtech.api.util.GT_Recipe.java :
there is a function isRecipeInputEqual (longer version) where fluids are compared:
aFluid.isFluidEqual(tFluid)
both fluids here are net.minecraftforge.fluids.FluidStack. isFluidEqual compares only fluidID and nbt tag (at the most recent forge version on github).
Conclusion. Accepting oxygen to input hatch and using recipe to smelt steel uses different comparisons, and the first comparison fails. Maybe because oxygens are different.
Does the inputside of the hatch(square that normally shows the outputside) show in the direction of the electrolyzer?
Yes, but I'll try again (now with a pipe between them).
Edit. Very interesting. After connecting to server I found the oxygen inside input hatch. I used it up by smelting steel, then tried to make and transfer more oxygen from electrolyzer to input hatch. Without success. It looks like oxygen is transferred during chunk load, or something.
Another test. Some oxygen is ready in electrolyzer, wrought iron ingot in input bus. Reconnecting to server -> green UI light indicating that steel is being made.. Strange bug 
Electric blast furnace's input hatch does not accept oxygen from directly attached basic electrolyzer. I tried both auto-output buttons, just in case.
I checked fusion reactor recipes. One uses lutetium, and I didn't find how to get it.
I'm not sure it (IC2 pump) can pump out big bodies of water. Or can it now?
I play with finite water.
What do you use to pump out oceans on Kirara?
I noticed advanced handpump in config. What is that?
We have carpenters and things, just no nei plugin. Use the wiki to find the recipes or install the correct nei plugin (is that even available for 1.7??).
I successfully crafted peat engine (recipe from memory). NEI doesn't show that recipe. Very strange for a crafting table recipe.
I noticed that you, Kirara players, use forestry. I tried it today and found that many recipes don't work, even for carpenter. I only tried to get a recipe through NEI, not actually craft it. I also tried to run just forestry and NEI - same problem. Is it just for me?
I use forestry_1.7.2-2.4.1.27.jar - the same as in your server's mod list.
Edit: I cannot craft carpenter machine.
I tried crystallyzer (with GregTech installed). NEI says that to crystallyze 2 coal I need 6000 EU. But it took 76800 EU (12.8 times more). I provided power from CESU through insulated copper cable into crystallizer, having one transformer upgrade. Mod versions: all the most recent 1.6.4 IC2, GregTech, Unidye. Is this a bug or a feature I don't know about yet?
