Ok, I didn't REMOVE or ADD anything in FH for a month, and today, I randomly got this error:
OGRE EXCEPTION(4:ItemIdentityException): ParticleSystem template with name 'RunicRing1' already exists. in ParticleSystemManager::createTemplate at c:\Ogre_161_tag\OgreMain\src\OgreParticleSystemManager.cpp (line 273)
Please HELP!
