x'D Your exports folder doesn't contain repeating particles. Go into C: >>> Feralheart >> media > particles and delete any ending in _0, _1, and so on.
Sometimes particles double when they are exported, causing the map to crash. Particles can also get themselves into the my_objects folder, so it wouldn't hurt to check there. ^^
Also, make sure your map is 513 x 513! That's very important.
If you don't find particles in those folders, search them in your PC.
Lastly, does your map have many objects? That can cause the map to crash.
Also, change your rendering system!
Thank you very much, after deleting multiple particles, it works smoothly.
