aww, you're right splo about the RETURN_META
the problem with grenades and breakables is quite hard to solve, and it's the same problem in fact: the plugin needs to guess whether the bot is aiming at something or not, and switch the aiming accordingly. When you shoot a grenade, your ideal angles aim upwards, so it's hard to tell with a traceline that you're in "fighting mode". Same for breakables (but I can do something for that case).
I'd enjoy demos of the bots shooting above the head and the other problems.
