Particle effects carrying over to other weapon models?

[spazthemax]

I have made a custom model to replace the gravity gun in a mod I'm working on, but unfortunatly I've come across an unusual problem. I've made a particle effect that emits constantly from a custom (not pre-existing) attachment point. However these unwanted particles only carry over after the model intended to use them has been drawn and switched away.

Here is the intended model with the particles:

Here is the .qc file, incase it can help at all:

		name			"glitchglow"
		attachment_type		follow_attachment
		attachment_point	glitchsource
	}

}
event ACT_VM_RELOAD 0 "glitchholdglow follow_attachment glitchsource"
}

Any help would be appreciated.

Edit:

FYI anyone who may have this problem in the future: I solved this by switching the emitter's duration from 0 to 1, and then reapplying the effect at optimal times during the animations I wanted. Here's my .qc as a reference.
