Ok- I want my time back.
Both the past 2-3 hours last night and this morning I spent troubleshooting;
And the next 1-2 hours I'm going to spend moving custom maps, sounds and models.
(Why so slow moving? Because I'm going to take my time..my original location contained some old stuff mixed with less new stuff, now I have to find it all)
Last night, I joined G4P's community server and saw errors.
Asked around to find out what model packs I was missing. As expected, Wire was one..found out Sprops and ACF were others.
I went online, got the appropriate latest repos' of them, put them in my steam/steamapps/<username>/garrysmod/garrysmod/addons folder.
Fire up Gmod, join the server. Still nothing.
Spend the next while troubleshooting.
Look like a noob to the G4p community.
Decide after some hours to sleep on it.
Get up this morning, start with a 'smaller' issue I'd noticed last night. Startup of Gmod was indicating to me that gmDoom was missing a iwad file I "knew" I had in the proper Gmod folder.
I go to the workshop to see if anyone else had reported the issue - well, yep. Up front and center in the main release of gmDoom it says, after the install instructions,
"If you decided to skip the above steps and open the garrysmod/garrysmod/ folder yourself, be aware that the path moved on June 5th, 2013. Follow the above steps so you don't use an old path!"
TLDR-
Some higher power that be decided to waste my time by moving install location of Gmod.
It's possible your location may be different, but for me, Gmod is now in Steam/steamapps/common/GarrysMod/garrysmod/
