It's a bug in the beta version use the normal release for now thanks it's known to me.

Beta is for 10.x so it's very unstable still but as it's a working copy to make sure it run with all game versions going forward. Thanks though

This is happening on retail

Ya but it's a change I made In beta that's doing it on all versions as it's beta I not got around to push a new copy
