Running into the following crash with 8.0.1 and 8.0.0. I can't figure out where the heck this is coming from as this is the entire crash message (crash log is at: http://pastebin.com/swTErh4w)

Any ideas? (I've checked Galacticraft and the Mekanism folder does not exist in the jar.)

yes thats what i thought too, but

You should tweet a link to the download page for us lazy folks
[18:05] <Cracks777_> aidancbrady, ender io gas conduits are still crashing sometimes, like when you hook them up to a gas tank.
[18:05] yeah - we’ll have to wait for them to update
[18:06] <Cracks777_> ok,
[18:07] it looks like tterrag1098 already has it fixed in development: SleepyTrousers/EnderIO-1.5-1.12@752342d

it did fix some things but didnt solve all the problems so we have to wait for ender io to update the api

Added a null check, don't know how this could happen though.

mekanism has updated there api and most mods that connect gas to have not updated there api yet, so you crash? are you using ender io?

Yep, but this is also with 8.0.1 which as unpairedbracket commented in your report to EIO should have had backwards compatibility added (SleepyTrousers/EnderIO-1.5-1.12#2141)

Was this null check add in 8.0.1.198? If so, the crash is still present. Thanks for the fast response!
