That issue is the wrong forestr API version. GT5 needs forestry 4.1 or 4.2.
Alternatively you can disable the GT Bees in the config, but then you will also not be abke to use Forestry centrifuge and squeezer recipes in GT machienes.
Thank you, that fixed it 
I am having this crash report, on a clean install and it only happens when I install Gregtech. If someone that knows how to read this could help me, I would really appreciate it. Thanks for your time.
Crash Report (Pastebin due to length)
Is this still a thing? The thread hasn't been updated in months and the IP gives me an error. Did the server get taken down or what?
I could translate to Spanish if it's ever needed, and there are a lot of Spanish players who use IC2 but have no idea how it works and have no English level, so they can't use the wiki.
How about this: Laser Etching device, right click on a block and it gives a transparent coating, you can then use spray paint to right click on each pixel to colour it, right clicking with red on blue would slowly make it purple then red ect. a nice painting device ;p Then you could add paint remover which can work on CF foam to remove the Obscurated stuff aswell
Woah this Idea is AWESOME! This way we could make ACTUAL paintings in the walls.
I wonder if the cross breeding could be made quicker in some way. Because I don't want to stay a few hours looking at my plants grow to get stickredd, much less to try to get hops, ferru, redwheat, etc. At least Gregtech adds more variety to make it more interesting, but it still seems really boring to me.
I sometimes use the terraformer when I don't have the time to manually flatificate the fields. The crops result so hard and boring to me that I usually stop after a few hours. Idea : Terraformer is quicker (maybe with a bigger energy cost?).
I was wondering if anyone could make a patch for the love&tolerance texturepack. It would be Ic2 and Gregtech textures.
Texturepack : http://www.minecraftforum.net/…8-151-16x-love-tolerance/
Solars. A lot of solars. And maybe a few reactors.
I would love radioactivity to be in IC2
Thats nice you can put a link to the worlds download.
Drill : Rock Bottom
Chainsaw : Creeper's Nightmare
Batpack : The Batman-Pack
THIS
IS
AWESOME!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
It was a tutorial. Now its a random stuff discussion.
Yes, there is such thing. But I doubt he is one.
I know almost all the vanila craftings, like the 80-90% from ic2,like the 40-50% of gregtech,all the bc craftings,like the 40-50% of rp2...So yeahi think im a pro crafter. If you wait two or three months ill be the Master of the Crafters 
Ok guys if you dont like the tutorial then how do i delete it?
Seriously o_O ?
Watermills, for now, are the worst generator ever:
1) Unmanned setups using RP2 habe been nerfed and now, for the lag (graphical, mostly) it creates, it's not worth to use that. And their intended way of generating infinite energy is ... half bugged, half useless, since you'll need 2.5 of these to get the output of a solar pannels, assuming you're not sleeping etc ... and, it's a real pain to set up (you'll need tower, cables, water ... It's not THAT expensive, and quite easy to understand, but that's a bit boring and bit longer than just putting solar pannels ^^)
You'd better use Geogens (from RP2 Volcanoes/Vanilla lake, assuming you're using at least BC, and that, even if you're not, tin cells aren't that expensive), they output a nice 20EU/t, with 5 Coal/Charcoal=1 Lava bucket/source/cell (in terms of EU generated, of course), and if you're kind of a cheater, you can even power these by lava lakes from the Nether and teleporting the lava with any Tesseract or such ... AND, even if you're not using these, you can just live in the Nether
If you're really a noob (which is very likely to be, if you're reading this thread with the purpose of learning IC²-Mechanics, you COULD use some Solar Pannels and spamm it, but I would instead higly recommend you to use the SpwnX-tutorial for Windmills, or to use some Nuclear Reactors (the funnier ^^).
No BC
Ans think that I´m using gregtech so solars need blast furnance and electrolyzer to be made. Reactors are a lot of copper and shit so this is why youre making the factory. And you cant set up a sky windmill base. So watermills are a good renewable power source for now.
And if you dont like my tutorial first wait for it to finish, as im actually a bit busy at school. And if when finished you still dont like it then dont read it.
EDIT: If watermills need aluminium then i didnt know but they are still easy to make and set up.
This is my first tutorial. Enjoy it!
In this tutorial I'm going to teach you about making factories. Since the small factory that only macerates and smelts stuff to the big one with its own self-refilling reactor,uu crafting sections, it's own mining zone, etc.
For this tutorial the mods I'm going to use are IC2 (of course!), Red Power 2 and Gregtech,since they are the ones that do better this work.
0. Preparing
1. Power source
If you want to use the miner you should use a normal chest, and then pump the stuff out from it.
