I brought some tar to fuel my endothermic fire pit inside of the volcano.
Every time I try to use it it makes my game crash. Can't even move it around in my inventory. Can't drag it out and destroy it neither. When I click on it the game just crashes.
It only happens inside of the volcano. When I go outside it works just fine.
I din't play with too many mods, but I disabled the one I have to make sure that is not what is causing the issue and made a new world. The problem remains however in the new world too.
Steps to Reproduce
Get some tar. > Go inside volcano. > Try to use it/move it around.
This issue has been fixed in either a future version or updated in a previous version.
