huge shout out to Fraysa who helped me solve this problem , its basically his fix

Hey man, Just clarifying that it's not my fix, it was made by another guy, but I'm glad it works.

Alright deleted the folders. It's downloading them again :|

it does re-download some files but after that it should hopefully work

Fraysa thanks for posting it, after days of looking and trying countless fixes i was sure what i found in your post was my last resort i was not expecting it to work.

in my folder it doesnt have 0.0.0.186
it got 0.0.0.172. I delete this folder anyway just to c if it works but it does the same thing except i get 0.0.0.172 back instead of 186. Any suggestions?

I didnt have any of the files/folders in the Deploy folder. So what should i do then? I found the other two things and deleted them but i couldnt find anyof the thinsg listed above in my Deploy folder.
