When look at stats in Unreal Frontend, can see the events that run in the function.
It work in 4.21, but it doesn't work in 4.22.
1. Create new blueprint actor.
2. Add new function to increment int value.
3. Connect function to event tick and for loop.
4. Placed actor in level.
5. Run PIE.
6. Exec "stat startfile" and "stat stopfile".
Then, expect to display increment event call in function.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-85184 in the post.
