server log (client with same errors)
2022-01-01-7.log

Same issue - version 1.07 on Fabric 1.18.1. Was hesitant to update since no change log was provided, but tried anyway. Reverting back to 1.0.6a resolved the issue for now.

Thanks for reporting, currently fixing the issue.

a fix should be on curseforge in a couple of minutes.

Please test if this fixes your issue, thanks.
