Yes it was a bug when updated to version 2.0 because the prototype was basically being copied into the original one which isn't a good option to do and isn't safe, now the mod depends on CharacterModHelper which is a much better way to handle it.
For character selector we are still waiting for miniMAXIme so it can work properly.
Please update to version 1.1.0 and check if it is working now, thank you for your report.
