this custom build is pretty awesome, and has some cool additions, i get way more resynchs with this than regular uncapped. though that is minor, it happens frequently enough to the point it's annoying. on the other hand, preventing the same file from being loaded multiple times is a very smart feature, and it's even saved me from breaking an addon by having multiple instances of it. unfortunately, this feature doesn't check for music wads, so it wont let me add multiple of the same music wad at once. overall, pretty cool
Also, the menu language is there because the current build was released for April Fools Day. There was going to be a way to switch the menu titles back, but I wasn't able to implement it in time. However, the full release for 2.2.13 will have a way to change all the menu titles back.
