Feral Heart

I have been trying to get into this map but every time I try it says something about a server problem but my wifi's fine. I installed this map from a .exe file, and there's supposed to be more maps inside there. Every character I tried to enter there with is now stuck on the loading screen. How can I fix these problems?

After I used the map maker and exported a few maps my characters have not been walking normally on any map. I checked the controls and they're fine. When they're supposed to go to the left or right they just spin in place. I've never had this problem before and they're doing this on all camera views. How do I get them to walk normally again?

The Portals

How do you delete an item from the map maker?

How do you install a new map?

I downloaded the .exe files for Feralcity and the movie theater, but how do you get to them?

Thanks for the help.
