Can't find Addons

ok I just updated Gmod today and when I started the game, I couldn’t see any addon I put in my addon folder.
my gmod folder became garrysmod_old or something like that,.
I remember that a message box with “converting gmod” or something like that failed when I was updating,.
so is that the cause of the problem? or I’m missing something

EDIT: ok,. I found out why,… the game’s directory was in common,. why is that? :confused:

The game’s directory is supposed to be in common because of the new format update.

ok,. thanks,. I guess I should just transfer all of my addons and maps there : p,.
thanks again!
