Fixed:
- Remove all in settings not removing categories
- Major issue with 2.2.32 that SRM would not save unless user had non english characters or emoji in their steam category names (honestly.. don't even ask). Mea culpa!
As with 2.2.32 you may need to clear out the files in C:\Users\Username\AppData\Local\Steam\htmlcache\Local Storage\leveldb (~/.steam/steam/htmlcache/Local Storage/leveldb on Linux or Mac) in order for the fix to work. I recommend just renaming the leveldb directory to backup, opening steam and letting it recreate the leveldb, exiting steam and then finally using SRM. Check that everything is good and then delete backup.
