What you have to do is go to your particle folder (by default: My Computer -> C: Drive -> Feralheart -> Media -> Particles). Look at your .particle files. See any with a _0, _1, etc. behind their name? If so, delete them. These are copys automatically made (for some wierd reason I don't know yet - maybe a glitch?) and therefore are uneeded. Be sure you don't delete your main stuff tho, don't kill the original particle template.
