Hi, the crash happens when I check usages of Redstone Block in JEI.
(Only checking Redstone Block will cause this, others won't)

Crash related mods:
NuclearCraft
EnderIO?
JEI
IC2

Crash Report: Pastebin

Same issue, but different fluid: https://pastebin.com/JgQgP4V8

EDIT: Can't exactly remember which block I pressed the usage key on, but I do not think it was redstone.

Yep, this is a known bug and will be fixed in the next release, which has been taking a while but will arrive shortly :)

Fixed in v2.11 :)
