Event Tick Stops Firing

Hello community,

I got a problem with the Event Tick and also with AutoPlay Timelines. These Events should fire every frame or time, however in all my projects they did work well. In one project these events stop firing afer about 1000 frames and I can not find the reason. I work with the VR Pawn from the template, but I did it in former projects too, so I do not see any connections. The only thing I found out was, that it is maybe related to the settings in the GameMode, but I never changed anything. I hope someone can help. Thank you.

I found out the solution myself. On Level Blueprint an Initial Life Span was setted. Turning this to the default value of 0 fixed the issue.
