I'm afraid the only hope is that the bot developer does extensive checks over all the bot source code to find the cause of your crashes. I can tell you already that a bot source code is such a huge thing it is only reasonable to assume there are SEVERAL crash bugs, and not just one to find. That doesn't make them easier to fix...
If I were KaCaT, I'd check all my pointers for nullity, all my angles for possible overflow, and all my edict_t pointers with FNullEnt(). It's a huge work, I know
*edit* and all my arrays[] for possible overflow too
