Hi I believe I have found a sort of edge-case bug but nonetheless annoying. The thing is I am trying to make a character. First through Charactermancer, a rogue. Then I level up the character through charactermancer+ while also adding a few levels in ranger. But charactermancer freezes at the building step. Then I tried adding one level in ranger, same issue. Then I tried multiclassing into other classes and that worked fine. I have tried multiclassing into ranger a few times now but it doesnt seem to work. How to replicate: Create character Open charactermancer and make a rogue. Go through steps Open charactermancer+ add 4 levels to rogue,multiclass: select ranger and add 3 levels. go through steps and see what happens.
