Thank you for reporting. I'd like you to attach a full debug.log if possible.

I recommend you drop your debug log here for the owner. I have other mod issues I'm trying to resolve. if you still have you log that'd probably be best.

I think the full log is unnecessary. Only one line is useful
[Worker-Main-9/WARN]: Exception loading blockstate definition: 'lava_walker:blockstates/modded_obsidian.json' in resourcepack: 'Mod Resources' for variant: 'age=4': Unknown value: '4' for blockstate property: 'age' [0, 1, 2, 3]
means the inside resourcepack of mod goes wrong. I think just modify assets/lava_walker/blockstates/modded_obsidian.json and delete the line about age 4 can remove the error.

I've left the error untouched because, as far as I know, it doesn't cause Minecraft to crash or behave strangely. I'll adress it soon if there are no other issues to look into.
