My timeline still fired the finished event even though it was stopped twice. I made me a print for Play From Start, for Stop and for Finished. So I can be certain that it got stopped twice and it still fired the finished event.
While trying to making sense of it I found this: Timeline not working - Blueprint - Unreal Engine Forums Jacky there mentions that timelines can get broken sometimes. I can’t remember If I copied that timeline somehow though.
I then made a clean new timeline and setup everything the same as I did with the “old not making any sense” timeline and with that it suddenly worked as expected.
The timeline just has a simple float curve and is inside a child actor blueprint of the player pawn. I had created this timeline in 4.11 as far as I know and I work now in 4.13.
I attempted to reproduce this but I wasn’t able to get your results. I’m glad creating a new timeline fixes the issue for you, but if you find a reliable way to reproduce the issue then we can investigate further.
I think it’s just an anomaly where a timeline was copied and then there was a code change in a later build that didn’t agree. I say anomaly because it doesn’t seem to be easily reproduce and I would imagine we would have gotten reports about projects breaking from across the board when 4.13 released.
But in the meantime I’ll keep an eye out for any other reports of this.
It just happened to me too, my Timelines made on blueprints I created yesterday. I saved everything, closed the project used my pc for a while and went to sleep. Today when I started the project again the unreal and tried to play test it showed me errors and it said only the timelines created yesterday got corrupted. Their names were changed to “Add Timeline…” but attempting to create another Timeline and naming it to the original name makes them Both get named the same and another error appears where the Engine stated that there is 2 statements of the same Timeline. Also attempting to add or edit tracks on the new Timeline result in Engine crash and so do trying to copy/cut the corrupted Timeline.
Since I didn’t commited the last night changes the only fix to it was to delete the old Timelines and remake the new ones with a different name.
