After I made or edited a map with sapien. I then used the tool thing to use it for playing in the actuall game. After I used the tool I then played the game, went to multiplayer, maps, but it didn't show. The maps name was "1234." Though it don't show. I don't know if I skipped a step, or did something wrong. I am thinking it's because the game only allows a limited amount of maps which could be it. But even if it is I don't even have an idea on how to remove them. Please help if you can.

Did you actually compile it?

tool build-cache-file ***path to your scenario***

If you did this and it's not working, it's more likely that the map just didn't compile because of errors. Fix those first.

If it did compile though, theres a chance that the map ended up in the virtual store folder.

C:\Users\username\AppData\Local\VirtualStore\ProgramFiles etc...
