We're still working on the port, progress should pick up soon.

AFAIK most of those issues are due to event ordering issues (including the various load/validate notifications on the TEs) or even missing events.

We don't always see a reliable load -> unload -> load -> unload order, but glitches such as load -> load -> unload -> unload, which makes it very difficult to reliably maintain a representation of the energy grid. Likewise, the wrong world warning in your logs indicate some sort of missing or misplaced event.

We can only further improve our workarounds, but until we're done with porting to modern MC further work in this area will have to wait.

We're currently busy porting, which isn't very approachable for newer devs. I recommend playing around with creating smaller addons or mods first to get more familiar with the ecosystem. Pretty much all successful newer IC2 devs went this route, the others were apparently quite overwhelmed with the complexity and learning curve of a >100k LOC project with some nasty dependencies (obfuscated MC with increasingly obscure code, lots of libs).

Sounds like a bug, not sure if there is a better workaround..

shouldn't it be "railcraft"? The command "/ic2 currentItem" should show the proper entry for whatever you are holding.

IC2 will most likely go straight to 1.15 or 1.16, depending on when 1.16 hits. It takes its time due to some re-architecturing and time constraints, but it should get there..

You can customize ic2's recipe configs by copying the one you want from the jar's assets/ic2/config to your config dir and adding the new recipes. There is a fairly extensive description on top of the file.

Yes they are NBT based. For the IC2 recipe configs the special format ic2:fluid_cell#ic2air (fluid name is ic2air) would work as well.

You are using IC2 classic, not regular IC2. Mekanism may only work together with the latter.

Uranium ore doesn't cause any negative effects, only its highly refined products, so this shouldn't be from your mine. Someone must be dropping some processed radioactive products into your inventory..

The system is arguably much more balanced than what you may have seen from other mods, you are unlikely to see quick easy gains. This is meant as something to do on the side while playing the game normally, gradually improving when maintaining the crops properly. Cross breeding chances favor higher similarity, comparing properties, attributes and tier to the base crop. Some crops additionally have special requirements to be selected at all.

It is hard to say, is the large idle heap use really a problem for you? It normally doesn't matter for a dedicated server that isn't oversubscribed with other tasks.

You place at the normal (1x) sticks, the crossed/doubled up ones are for breeding two adjacent crops together.

If you remove the arg and run "/sampler gc" or "/sampler memory --gc", Sampler will trigger a full GC run that gets rid of excess memory allocation. It looks like your GC config (JVM flags) isn't very good at reclaiming that memory by itself, it is too passive. You apparently had to wait a very long time for old gen GC to kick in without this provocation.

Make sure to pass the nogui argument to the server command line, otherwise the lack of "-XX:+DisableExplicitGC" causes lag spikes due to the poor GUI code forcing GC twice a second... With nogui the arg shouldn't have any positive effect.

The numbers look very good otherwise, just 412 MB of actual heap use. Everything else was transient or too lazy GC.

Install sampler, remove -XX:+DisableExplicitGC and check what the "sampler memory --gc" command outputs. This is probably just peak memory use during startup remaining allocated due to your JVM config. How are you measuring memory use?

I am btw unaware of very high mem use from IC2, even during startup.

It needs to be a mod/addon, profiles don't really add new content afaik

You should be able to add them similar to iridium ore in IC2.ini (in [balance / uu-values / predefined])

Forge 1.14 is unfortunately still quite far from what we need, especially our armor hook is quite important yet nowhere to be seen. The vanilla side isn't particularly stable either, making it a somewhat undesirable to rush a release.

It is Optifine doing all the shadow handling and FC disables most of its render optimizations with OF+shadersmod present,. I don't know what's wrong, maybe the player gets culled by FC in the shadow pass. I'm busy working on FC2 for 1.12.2, so unfortunately this bug can't be fixed at this point.
