I was reviewing the logs to track down another bug and found a lot of this:
2019-10-08 23:28:50 WARN - Model AresMUSH::Character failed to respond to scene_participation_count undefined method `scene_participation_count=’ for #AresMUSH::Character:0x000055cdc494a380
Did you mean? scenes_participated_in=
Reviewing other logs it seems to be happening almost constantly.
