So you are using a control rig in sequencer with it not being in any blueprint at all?
I had something like this happen, but I had stuff in blueprint that had tick timings as opposed to the sequencer timings. I think they added stuff in sequencer since then to fix most of that, but without the right settings it could probably still happen. If it’s not that I don’t know what is going on. It’s also really hard to say off of a few pics. No overview of your project and files and everything.
There is a lot of hidden nooks and crannies in unreal. Time to start looking in those.
