Game crashing

Hi it’s me again D= I’m having a problem where the game crashes when an enemy uses a certain move. I’m not sure what the problem with the code is. Heres the code:

 
_global.especial=2
_global.especialtimer=3

It doesn’t seem like much but it affects 10+ movieclips every frame which might be whats making it crash. All my enemies fx have this on the first frame:
gotoAndStop(_global.especial)
which makes it go to the second frame when the enemy uses the move “flame surge” Basicly the move works like a special tranformation, but because of all the fx that is used to make the enemies flame (or my guess is), it makes the game just freeze. I’m sure theres a better code for this, and I could use some help. Thanks
