As the title says, the client crashes as soon as i place a Melter on top of a TCon tank (filled with Lava) and the Client keeps crashing (with the same exact error) when i try to rejoin the world,

The dedicated server i'm using is not affected by the issue.

Contains the full client crashlog and a partial log of the server, at the time the crash was happening.

MC: 1.12.2
Forge: 14.23.5.2814
TCon: 1.12.2-2.12.0.135
TComp: 1.12.2-0.3.1

I'm going to leave this open for now as I plan to release a 0.3.2 to address this issue, rather not force people to update to the alpha to prevent a crash. Glad to hear its fixed in 0.4.0 though, means I am right about the cause.

Nevermind, overlooked the 0.4.0 alpha, am no longer crashing and i don't see any obvious issues with the current alpha.

Released 0.3.2 which addresses this, so the alpha is not required to be compatible with the latest Tinkers
