Try changing your rendering systemThats what i would do or see if something is in the wrong folder
I will try to help here. That seems, not so good. My only guess is that maybe some file ended up where it isn't suppost to. Is a pop up appearing saying, 'FeralHeart.exe has stopped working' or is the map server just losing connection?
Particles can sometimes end up in other folders, not just the actual particles folder. Try looking at other folders in your FH files. ^^
I'll edit this if I think/find anything else.
This has happened to me before, I belive it is a problem with "wine". That was what it was for me. If you have this try downloading "WineBotler"
