Made a few cone cows and toy chariots while waiting for inheritance to become available, spawned in, but the timer ran out but they are just left sitting there in study window. Popping them out and trying to study them again does not restart the timer, nor anyone else can study them.
Also, skills learned during that time get overwritten and unlearned but the quests remain active but un-finishable until re-learning the related skills.
Oh, and learning swimming and going over river straight down the middle does not result in an ambiguously gendered character model. Literally unplayable.
