Not sure what mod has incompatibility but hope someone here has more knowledge than me. I cant put any items into the 3 input slots on the architects chisel so i cant craft any blocks from the mod. Playing Valhelsia 5 v5.0.3 with rubidium and oculus installed

Forbidden and Arcanus is probably the one causing the issues

seems to be an issue with Forbidden & Arcanus yep

This has been fixed in the latest update of F&A nothing we can do.
