Fps drops down in my game

Hello animate team!

Currently working on new mobile game. Few days ago i installed update -  animate2018 from animate 2017.5 and i discovered that when i was adding new code to game, in some specific parts of gameplay where i add code - fps drops down even if i switch code to comment later.

I reworked  my code all day - still was a problem.

So i uninstall animate2018 and install 2017 - and this helps! No fps down with zero code changed.

So now working with 3 days later - the same problem appeared again and now with 2017.5 version.

Dear animate team, can i send you fla files with my game, so you can view it? Im sure its a bug. I worked on a game a few months and dont want to ruin all my work.

Thnks, Pavel.
