I'm in generation 3 of my dynasty and suddenly my sims are sinking into their beds, not sleeping, just lying and deteriorating their needs. Resetting works, but once this starts, they and other sim townies randomly get "stuck" in patios, disappear or just behave oddly. I do not remember doing anything specific before it happened, except doing a lot of portraits and purchasing the 5th and 6th property/building. Should I just keep resetting them or is this maybe the mark of The Inevitable End?
