Hello there! Welcome to the forums.
There was a thread exactly like this 3 days ago. Have a look at the solutions there. It’s something that comes up a lot, and is fairly easy to resolve.
I’m curious to see what you mean re: hit and miss decals. Is this just with regards to taste, or quality? I just received my DEOT gameshell this morning, and the quality seems to be on par with the standard one.
