Monster skipping frames etc.

[Guest]

I have a weird problem, I donwloaded custom monsters from realm677 called Archon of hell, then I went into nerfing it so it is not as strong.
The monster act as it should most of the time, but on some occasions, it skips some frames and use only last frame when doing a_custommissile, or it even throws the fireball in different direction than it is facing. What could cause this behavior?

Here is the code I am using:

It happens because Missile state have a bad A_Jump offset structure.
