On the latest version 0.3.11-lite.20201231 I have critical issues.
Export functionality is not working - the application just hangs after I click the big Export button on the export panel. Also after any change done to characters, the application hangs in a similar way. Though this could be fixed by trying to close the application - it will show "Save changes" prompt and will hang no longer, so I can just cancel it and continue.
These issues are present for both previous characters and newly created.
