Mod versions: Industrial Upgrade 2.4 RC 4, industrialcraft 2-2.8.222-ex112
first, your mod is incredible thank you for this mod and your work :D

i have a custom modpack and today it crashed on my server and i got this crash report, in the meanwhile i use the RC 3 and wait to the next version, so no pressure from my side :D

oh that was quick, so but i have another problem, somehow the server is starting but when the world is loading the server is crashing again with this crash on multiple things:
net/client/util/ITooltipFlag
ic2 core block TileEntityblock
ic2 core TickHandler on world tick
at com.denfop.tiles.base.TileEntityBaseSunnariumMaker

and i have removed the things as you stated in the description
i don't know if this is my fault
one thing: client side it is perfectly fine but on the server it is crashing when the world is done loading
