opstack error?

[PurplWulf]

I got the text on adding bot support to maps today and created the route file for my map, but when I load it in MP, the bot works fine, but the map crashes with:

 

Opstack corrupted in Compiled Code (error message)

 

does anyone know what's wrong and if so, is there a way to fix it?

any help would be appreciated.
