BUG: Sims resetting when getting out of bed or when someone else doe

Every now and then when my sims gets out of bed (and has a few actions to do) they will 'reset' (as in what happens with resetsim... they stand up straight and all the actions disappear from the action bar). This also happens when two sims are sharing a bed and one gets up because they've got full energy or I cancel the sleep action.. the other will wake up anyway (even when not full energy and I haven't cancelled the action) and they will both reset.

Anyone else having this bug? Not a huge deal but annoying when I have a few actions in the bar.

When they both wake up because you wake one up, have they gone to bed together? I know that through Woohoo they fall asleep together, maybe the wake up is somehow related?
As for the resetting I have no idea, but now that I've thought about it, it has happened to me on very rare occasions.
I've always just shrugged it off and not paid much attention to it. If it's a bug everyone is having hopefully they will release a patch soon

No, they hadn't gone to bed together.. They work very different hours so one was always going to bed before the other. It's started happening almost every time anyone goes to bed now. Weird.
