Attached is the crash log from this instance

To recreate: place water above a copper symbol and let it flow down onto it, doing so crashes the game after a long pause

Edit: tested this with all other symbols and they provide the same crash message, albiet from a different block in the logs, attached is the occult one just in case this one is different

Oh! Good catch, thanks

It's a crashing bug so I'll release a new version whenever curseforge servers stop dying
