Crash when deleting timeline

Development Programming & Scripting Blueprint

I have a 100%-reproducible crash when I attempt to delete a Timeline object in one of my blueprints. I go to the Blueprint graph, select the timeline (which isn’t connected to anything and has nothing in it except for a couple of tracks), and try to delete it, and I get a crash (see call stack below). This happens regardless of whether I delete the tracks first and regardless of whether I attempt to delete it via the Delete key on the keyboard or by right-clicking and selecting Delete.

Hey,

Thanks for your report. I am not able to reproduce the crash you have reported with the following steps:

  • Create Actor Blueprint
  • Add a Timeline node to the EventGraph
  • Create several different tracks
  • Delete Timeline node from the EventGraph

I tried several variations on this, including compiling at different stages or not compiling at all, but have not crashed. Are there any steps you may have left out of your description? Have you tried to reproduce the crash on a new project with the same results? Any additional information will help me further investigate the issue.

Best,

Ben Halliday

Hi Ben, I really can’t think of anything, besides the fact that between adding the timeline & checking it in and the later crash, I added a few sound cue properties to the blueprint in question. Here’s a screen capture of the graph for the blueprint in question in case that helps any.

Hi there,

I’m experiencing this issue with 4.11.2 … Everytime I delete a timeline the entire Editor crashes… I’ve just left the TImelines in the BP as artifacts. Unfortunate, Unreal still has bugs like this 2 years since. Wish I didn’t use BPs honestly at this point.

Have you tried renaming the timeline?
