Whenever I crash my car, or a crash happens near to me I get the "Too many indices" error and my Gmod shuts down. Someone please help.
Never seen anything like that.
I've experienced it too.
After some researches i've found out sadly enough that it all depends on how powerful your computer is.
try to avoid crashes. ^^
Though one thing that may help is that you DISABLE all the addons you don't need. Worked out for me (a bit).
