Took a Melon Seed and attempted to put it on Crop Sticks; crashed immediately. Any attempts to load back into the game results in a crash as soon as the player loads in.

minecraft version, agricraft version?

1.7.10 Minecraft - Agricraft 1.7.10 - 1.5.0

Worked around the issue by adding the Melons to the Blacklist.

Thats not really a great fix though, remove whatever mod this is :
at mrtjp.relocation.ASMHacks$.renderTileEntityAt(hacks.scala:30)
at mrtjp.relocation.ASMHacks.renderTileEntityAt(hacks.scala)

and see if it still occurs

Good Question - One of these I suppose: https://github.com/MrTJP

A slew of ProjectRed mods are loaded. (Base, Compat, Integration, Lighting, Mechanical, World)

I'll give it a try during some downtime in the server population.

Alright thanks, I'm not going to bother debugging if that bug doesn't happen with a clean stacktrace.

@InfinityRaider
I just tried it again after removing the MrTJP core and all the dependent mods (project red/forge locator/etc), I will upload the log as a new error I guess.

Edit:
Please reference #687 for a clean stacktrace.

Alright Ill close this one then. Thanks for the clean stacktrace
