I was working on my map pack; the main map when all of a sudden, I get a pop-up on my computer. As usual, I just x out of the pop-up and continue on working, but this time when I x'd out the pop-up and went back to map-maker, my whole work had completely disappeared. I had saved everything and all and hadn't hit anything, the whole land disappeared as well as the objects and water. It's now just a sky.
I went into the map folder under FH>Media>Terrains and it still has my objects as being there and everything how I had it, yet the land won't show up. I've tried restarting and now I'm just ticked off. This isn't the first time I had to re-do my map and I was just about done. Either Map Maker is just a butthole, or it really is starting to glitch, but I'm hoping this can be fixed without me having to start over.
** Update; The map shows up when I go inside of it in-game, yet still not in map maker....
- Thanks for the help, Reidiculous.
