Now everytime when I try to manually save, the game freezes, on every save I have. This game is seriously buggy.

Does it freeze when it says "saving content do not turn off console"?

Hi,
The GAMEBRYO ENGINE in particular is very sensitive in scripting, so if ur messing around with the save games too much it breaks the game.
It′s not Buggy. (Imagine how much scripting in this open worlder is)

Just Do manual saves from Scratch and turn ALL Autosaves OFF.
I mentioned this in Detail in another post already, Sorry for that.

Funniest quote on here, ever...

Thanx Bro, youre Welcome.

That was only related to save game issues.
OF COURSE this game has a lot of Bugs!! for many people.

But New Vegas was running very fine on my playthroughs, i only use manual saves from scratch (all autosaves OFF) like i said in another post in detail already.

The GAMEBRYO Engine is very script sensitive, believe it or not.
I don′t wanna offend u in any way. It′s just a recommendation TBH.

Same Method worked fine for me in Fallout 3.
I played FALLOUT 3 with all 5 DLC′s almost flawlessly, even Mothership Zeta worked with no issues on my playthrough.

The Fallout World had Bugs from the very beginning (Quest Bugs most likely), bro i played the s*** out of this universe, (Fallout 1, Fallout 2, Fallout Tactics)
but i never encounter a Major game breaking bug. The Older Fallouts had more problems related to specific PC hardware which resulted
in a PC crash.

Long Story Short......
