Corruption playing certain graphics

[Skincanvas]

During the pinkacopter_left or _right.gifs is a strange corruption. The typhoon corruption happens during this animation, only during this animation, at exactly the same time. The animation even seems to work for a few loops which is the strangest thing, I looked at the gif itself in gimp and not a single frame is messed up. It is guaranteed to show up with 30 Pinkie Pies and you can remove it from poni.ini without problem, as in without causing another graphic to corrupt or something

Its probably not a longterm link, just a visual of the static/hard rain pissing sideways graphical error

I know what the reason is (wrong frame index being computed, which results in trying to read from a wrong place in a GPU frame bank). If you switch to CPU it`ll most probably segfault.
This is the consequence of horrendous quality of the code responsible for behaviour logic.
As is apparent from the commit history I`m not actively developing the project anymore, because why bother, but still I have a local branch where I attempt to fully restructure everything concerning behaviours/effects/speech and rewrite it in C++ where resizable vectors and hash maps are readily available.
