FPS goes down by time

i must have made an error in my blueprints. when i do “stat Game” i can see that the blueprint calls go up and up and my fps is going down. i tried to find the “hole” with the session profiler but i was not successful.
Can someone give a tip on how to use the prifiler in such a situation, or how i could find the problem in an other way?

That was indeed the cause. Spawning widgets in hud update function…

Sounds like you’re spawning objects that use tick, and they are living indefinitely instead of getting destroyed.
