For those of you who accidently saved your monster character and are now stuck with it. I had this issue and could only pick warrior. The GM's pulled my character out to test it was fine so I narrowed it down to the UI settings. You need to delete the section in your UI setting that reads [TaskTemplateSelectWnd], for me it was near the end after line 2000 or just search "tasktemplate" and that should pull you down to that area. Good luck
