From the looks of things, Fluorite's server must have reset itself. That's what will cause you guys to crash.
To retrieve your characters, go to the top right of the your screen, Login again, and in that yellow box to your right, click the "Character Reset" button.
From there, Login again and select "Reset Home" and "Go Home" on the characters you want back.
This should retrieve your characters. Fluorite will likely be back up in a little while, so just sit tight and check in after a few minutes. c:
However, if your game continues crashing for the next day or so, I would suggest uninstalling and reinstalling FeralHeart. This would resolve any issues within the game on your computer.
