Server Crash, Any Ideas?

[EmNudge]

I'm not the greatest of mappers, but I make one for a community. The server we use has crashed 4 separate times with a unique error message. Google searches concluded it was a sourcemod issue, although the owner of the community refuted this.

Here it is:
L 07/29/2016 - 07:26:59: Engine error: SV_PackEntity: SnagChangeFrameList mismatched number of props[22 vs 94

any ideas as to what's causing this?
