    Running UE4 4.15.3, and Spine 3.6 (also 3.5, this crash is why I updated to 3.6, but the crash persisted), I get an editor crash after an indefinite amount of time (sometimes a few seconds, sometimes a few minutes) of running a map with a spine object in the scene animating (the powerup example provided by spine). Here is the stack trace of the crash:

    Access violation - code c0000005 (first/second chance not available)

    oh more info. the line that it breaks on is:

    ConstructItems<ElementType>(GetData(), OtherData, OtherNum);

    where "OtherData" seems suspect:

    Hm, I tried to reproduce this with the sample projects, but got no crash (UE 4.16.1, latest Spine Runtime from 3.6 branch). Could you provide me with a small project the reproduces the issue? Do you have a Blueprints or C++ handler registered to receive animation events?

    sorry for going silent. Because of this crash, I decided to work on other things. On return to this issue, the crash seems to have disappeared. I'm not sure what has changed (I didn't change anything as far as I can tell). Maybe updating Unreal Engine or Spine has resolved it. Regardless, this doesn't seem to exist anymore. Thanks for the reply.
