Thanks again for the reply. Sending the bug report your way in a bit.
As for the Summer Event. When I initially got the quest. The event ended and it disappeared, next time it showed up, it was already completed by the looks of the bunny girl under the bar counter. I did however unlock the clothes every day after that point. Everything except the pony tail hair style. So I think that might be bugged too?
Edit: Bug Report has been sent your way.
