Voxel
Oh i found how to cause it:
You just scrub really fast through the demo timeline, dipping into where the team was formed and out of it
Yeah I noticed that too, When I had something fixed in the demos the other day but didn't look into it more, I think that was always the case xD If you have started the recording before you are in the team and if you then view the demo and jump forward in the timeline, the tees are often not yet in the team.
