Weird, Model Deforming glitch, I have lots of addons, and wont stop.

The glitch was, Everything was great, it was fine, but then, Eventually, I swapped to the gravity gun. it had a weird aim thing at the top, I then swapped back the the revolver 357. Then it went ahead, and deformed the model, removing the ammo holding thing that holds all 6 ammo slots so it can fire, then It removed it, made it look wierd, then only spawned 3 bullets when i reloaded. It also effected another half life 1 weapon mod, so that the sleeve doesnt appear, when reloading the magnum. I really want an answer, it all happened when i disabled family mode on steam, then it went ahead and deleted lots of game files, What makes this a game breaking garrys mod bug, is that when it does it, i have to validate, to get those models back, do the same thing, make the bug occour with the games files, validate, Rinse And Repeat. Answers Would be wonderful. I only really need answers for the garry's mod end, But if possible, Also provide answers with my steam problem, if this is allowed in the forum. Don't Do it if not allowed, because i just signed up so i can report this problem. If i dont get an answer within 3 weeks, i will publish a double problem with all this info, on a steam forum.

The addons thing, is alot of addons. I haven't checked my addon section, as it might be the problem.

I just replicated the glitch, it went back, did it again, and then i went ahead and opened a addon section, and now almost everything that has reflections, or mirrors, are missing textures.

Also, I think it happened a day after i disabled steam cloud.
