Hi,
Recently I ran into an issue where I can’t load up some maps on 4.7 that previously loaded fine. I’m using latest GitHub build for 4.7.5 but last official 4.7.4 had the same issue. One map loads fine, but a couple of other maps crash on startup whether I try to open them from the editor or set the editor default map to be one of the ones with issues.
