One of my players is experiencing a consistent startup crash with this mod (v1.8.0) in the TerraFirmaGreg modpack (v0.7.14, MC 1.20.1). When he disables just this mod, the game starts normally. When he enables this mod, even after updating to 2.1.0, the crash happens. Here's the crash report:

crash-2024-12-07_18.16.31-client.txt

Any help is appreciated!

His config files must be corrupt, tell him to delete the additional placements configs and let them regenerate, and see if it still happens. If it does, have him send the config files (just the additional placements ones) over.

That fixed it. Thanks!
