Throwcallback problem

I have extended my AIplayer class to use a hovervehicle and it is now uses an AIPlayerData datablock instead of using the hovervehicle datablock. Now I have some custom callbacks to script that aren't always being called. I have a function in my aiplayer class that checks the distance between it and the player and if it can see it and stuff so it nows when to move/fire ect.. Now the function itself seems to work because I have the aiming inside that function and it always aims. The callbacks I am using in script handle it's movement and firing. Sometimes when the bot is spawned in it just sits there. Now I know the engine code is working because it is rotating to face me but it won't fire or move when I'm within range. I added in some echo in the script callback functions and sure enough that function wasn't being called. The odd part is that sometimes it works perfectly and other times it doesn't do the callback. I tried putting in a straight Con::executef(...) and the same thing happens. I'm not sure why sometimes it calls the script functions and sometimes not. Any ideas?
