Subject: [PATCH] TG: - you can now only have ONE decal of blood per tile. This
 is to fix the millions of blood effect items that spawned to lag anyone who
 right clicked them. The most recently created blood item will be the one that
 remains. This does not effect gibs. Revision: r3490 Author: 	 baloh.matevz
