I'm not sure if this question was asked and answered already. If it is, please tell me.
Okay. I made a map with snow in it. I went to went to Sky maker to make and save the file for a snowy weather cycle. Everything went fine. I put the file in my map and on the map maker the weather is snow. In the game it's rain (This is NOT my actual question) I wanted to go in the Sky Maker again to see what went wrong. When I tried to get in Sky maker it gave me that FeralHeart.exe something message.
