There should be a way for the game to detect custom levels that you've already scanned so that you don't have dupes. It's too hard for us to know once we get into the 100s...
There are so many levels in the forum that I import some times a duplicated by error. It would be nice if the game can detect such duplicate and avoid the import. Thanks!
I've been trying to cull my downloaded list of games for this reason. If there was at least a way just to search the list, then I could do that prior to mistakenly downloading a duplicate.
