Help with making a map

so im making an edited version of the island, and heres what ive done

-made a new folder in the map section
-copy all of the island sublevels
-paste the levels in to my new map folder
-wait about 2-3 hours
-see that all of the levels have gone into the folder

my problem is when i try to save levels such as "A1_Near " it crashes my game, ive tried renaming the levels and saving it, and nothing works.
im kinda a new modder, though i made an OK map from scratch that ive never uploaded, but if anyone knows the solution to my problems, please let me know what to do.

Not sure but maybe put your new folder into the Mods section not the Maps section?

ive done that, but the same thing happens. am i doing something wrong?

First of all, your map’s sub folder needs to be in the “mods” folder, and not the “maps” folder. Only official maps should be in the “maps” folder.
