I've played this game 3 times but this has never happened to me before. I had quite a few subscribed items in the workshop. However, when I played Mod Blue Shift for the 2nd time, I downloaded the mod for other HECU soldier skins (https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=3379013472&searchtext=blue+shift ) and this is where all my problem started. When I compleated second gameplay of Mod and start my hunting for achievmants, the soldiers started to bug. Some of them had missing texture, so I deleted that mod. Everything run perfectly, but than... ... LOADING ... ...and my weapons were suddenly bugged!

Crowbar:
I had my trusty crowbar in my hand, but when I clicked the left mouse button, a sound effect played but no animation. When I hit the box, the box broke into pieces like a classic.

Glock 17:
My Glock was in my hand but there was no animation for reloading, when I clicked R for reload, the gun was loaded immediately in the second without without the usual waiting for reloading while starting the animation.

MP5, Shotgun, .357 Magnum:
same problem as Glock 17

and than the worst part:

Frag Grenades:
hands were shaped with fingers to hold a grenade, which was missing from the hand as if it were invisible.

Tripmines:
Both hands were on the screen in the shape of holding a tripmine but as with the grenade, again none of the weapons were in the hands, when clicking on the wall there was no connection sound nor did mine appear.

Other weapons:
I didn't have any other weapons because I was in the chapter Power Strugle

Please help me, I tried EVERYTHING like: unsubscribe everyting from Workshop, vertife game files, uninstall and install game again- NOTHING
Please understand that I can't play my second most favorite game after Half Life 2 right now because it's in an unplayable state. I would be grateful for any help or supportive comment.
