How to pinpoint source of big Tick creep during play?


my game has sometime recently started getting a fast and high increase of ‘World Tick Time’ and ‘Blueprint Time’ according to ‘stat game’, during gameplay and starting as soon as I start playing in PIE.
So I need to find out where this is happening.
I just checked if I accidentally spawned lots of objects but that does not look to be it.

What is the best way to localize a problem like this. I suppose I’d like to at least be able to see from which Blueprint this is coming.
How could I do that?

EDIT: Found the problem and when I sorted out my build errors I am going to test ‘stat DumpFrame -ms=0.1’
