Been having similar issues. I went to the creators of the regular Bridges version and have had a few other conflicts with BOP working with Bridges 3.0 when this one is not active. It refuses to load if this mods is active.

Updated in 1.20-1.2

Running 1.20.4 on the Fabric loader 0.15.9 and had the peoblems only 2 days ago

This issue has been fixed for Forge version with new 1.2 release. @Lord-Greyhawk the update was released more recently than that, please confirm if you are able to update the mod.
