Do not open the inventory while Sexiles is active. I suspect that this is what's causing it for you guys.
Are you getting stuck with thralls? If so, simply pick up the thrall to reset it and free yourself.
Try reactivating sexiles and deactivating it again (tab) when stuck.
Try playing an emote or equipping an item when stuck.
Is any of that possible?
Do you happen to know if there was "heavy" server use when the issue occurred?
I ran into this issue as well on a single player game. I think the issue was I activated, deactivated, opened inventory, closed inventory, then activated again, then after I deactivated I was stuck. Tried eating and equipping and unequipping gear. I was able to activate more scenes with the thrall but that was it. Will try picking up the thrall next time. This mod and pause on menu are the only two I have going right now.
Getting stuck with thralls (as in, you can DO stuff, your character tries to but can't move around, etc) is common. I can try and fix it but, honestly, eh, just seriously pick up the thrall and reset it for the time being.
If you CAN'T DO ANYTHING when stuck, as in, when you press W nothing happens, that's a whole different issue and I need feedback about it. Context, location, everything.
