Using 4.15.2 here and I’m experiencing several random sequencer errors in final builds. Some whole animation-tracks or sometimes the event-track are ignored on playing the sequence in a final build.
Every track in a sequence is executed in editor, but the final build sometimes skip some. Ir could solve some by simply do an arbitrary change to the bogus track (moving a key a few frames back and forth, or duplicating every key in the events track). But every build you have to test every sequence because there is a chance of about 10-20% that some animation from every single previously working sequence might be broken. We are doing some real-time product visualizations which include a lot of feature animation done by sequences and at the moment this error costed us a few days in production and a fair amount of trust in online-rendering.
Somebody else experiences strange (missing) behavior with sequences?
