Are you getting the first trig lighting yellow like I did?
I haven’t had the issue for a long time now but I recently dug out some old notes on OT bugs and I’d written something about copying a thru track to the adjacent track, turning it into a neighbour and setting it to plays free - pretty convoluted! I haven’t run into it for ages & couldn’t reproduce the problem recently so I’ve assumed OS update(s) have solved it. But maybe my notes were just not that accurate. or it’s more temperamental… anyway just putting that in here in case it sounds similar to what you were doing with the tracks
