The game crashed whilst rendering overlay
Error: java.lang.IllegalStateException: Failed to load description for particle forbidden_arcanus:soul
Exit Code: -1

I would need some more information (what forge version are you using, minecraft version, forbidden&arcanus version,...)

I am using 1.16.3 -forge- 34.1.29

i am using the most recent version of forbidden&arcanus

This ticket will probably exist longer than "the most recent version" is accurate. Please provide specific version numbers.

Perhaps a crash log? There should be a "crash-reports" directory.
