1/ the functional issue with interceptors staying on place after shooting down UFO is now fixed (or at least I couldn't reproduce anymore)
2/ there is still a visual issue that some interceptors are exactly over the UFO, but some are visibly some distance from it... I don't care as long as it works, but it looks funny. Visual issue can be seen here: https://youtu.be/3vngZKRhrWg
3/ this visual issue (and also the description of the bug in the tracker) reminded me that I also had an issue with skyranger following UFOs which land... the skyranger for some reason didn't start the mission after the UFO landed... and I could reproduce this now also on the newest buildAgain I used the same trick with "1 Day" speed, but I have seen it also on much lower speeds (e.g. "5 Min"), there is even a proof somewhere in my LP, but I don't know which episode. Anyway, this video: https://youtu.be/sE7k7foX98s shows the issue... I am doing the same there 3-times, first on "5 Min" speed, then on "1 Hour" speed and lastly on "1 Day" speed. First two speeds correctly result in a mission... but the third speed causes that the mission never starts.
