@Chi5678 It's not uncommon in my games for sims to be reset out of their beds. This happens most often when one of the sims doesn't "belong" in a particular double bed (whether someone's cheating or just single and having a sleepover), and when I've saved and reloaded during or after a woohoo. I usually don't have any long-term issues with sims affected by this, although sometimes it can be a symptom of a sim with a borked action/posture/inventory item—one particular offender is a sim playing guitar for tips when I save one evening, and then he/she gets hard reset by the game around 7 am the next day, with a shuffled inventory and rebooted needs. But if you're getting an error that reads something like, "ScriptError: Woohooer," it might be that when you reboot a save, the game reloads the data in a corrupt way that one of your mods is fixing.
Sometimes after this error, the bed doesn't work anymore—any action to sleep or relax on it is immediately dropped. I used to sell the bed and buy a new one, but it can be fixed using MC's object reset. Click on the ground anywhere on the lot, nraas>object reset>not inventory (if it's placed on the lot; if it's in the family inventory you can select "inventory" instead) and a list of objects will come up. If you have more than one of these beds on the lot (not just a double but the specific buy item, regardless of color scheme), selecting from "not inventory" will reset them all, so if you don't want to disturb someone else who is already asleep, drag the borked bed into your family inventory and reset it from there instead.
