Hey ,
I’m going to suggest that the other issue at hand is different than yours. Your issue appears specific to the fade track. If I add a translating cube to your sequence and play it again the cube will remain at its end position.
I’m going to continue investigating this AND the other issue, but I’ll be noting in the other thread that I may still need some examples from the other users who are seeing this with tracks other than the fade track.
I’ll let you know when I get back to this issue as I have a few others that require my attention first.
Thank you for your patience.
