If you make maps and exported a map recently, check the particle folder for water particle_01 and _02 and delete them.
If you do not make maps and it just started to do these crashes it's either that you use a rendering mode that your computer do not cooperate with, in that case you must open the ogre.cfg file with notepad and change the top row to the mode not selected. Save the txt file and start the game.
Or
That you added content or mods that causes the game to crash, and if you cannot backtrack the things you did and make it as it used to be, a clean install of the game should do it, just delete all the content inside of C:\FeralHeart, then download a game setup from our page and install the game with that.
