Here are a few things I've noticed: 1. After he started opening the shop 24/7 due to my fixing the community center, I visited Pierre on a Wednesday, where he proceeds to tell me something like "I'm so glad I have a day off!".... while manning the counter as usual. 2. Upon completing the last Crafting room bundle, the refurbished room appears: well, I got stuck into the chair that pops a little below mid-center of the room. It appeared on top of me and the game didn't move me, I didn't have a warp totem on me either so ended up waiting until 2am for someone to drag my unconscious butt back to bed. Both of these happened on PC with the latest Steam version, no mods.
