Hi @lightning02

Sorry, but we don't support Thermos/Cauldron/KCauldron /Craftbukkit/Bukkit/etc.

I'm closing this, but if you can reproduce this crash in a Forge-only environment, we'll re-open and investigate further.

@lightning02, This appears to be identical to an issue that we just fixed in our event manager. Try updating to RTG-1.7.10-1.1.0-snapshot-1

Note that this is a SNAPSHOT version, so you should make a back-up of your world before using.

Tryng to reproduce on forge would be painful and would take alot of time since this is a random crash, also, Robotia and other Thermos developers are really kind and open, I guess they would not reject further investigation and help other mod developers to fix any possible issue (if asked to them).
@srs-bsns thanks alot to have at least looked into the logs, I really appriciate, I will try this snapshot with a backup and see if the crash will still occur in the next days :)

I reopened this at #833
