If some map cause problem (crash the server) because of too much precaches, create a file
in your AmxModx configs folder named 'sensiblemaps.cfg' and add the map name (WITHOUT the
extension '.bsp') in that file.
So if the map is in the list, the plugin prevents trail sprites to be precached (i.e. the
trails are DISABLED for this map.
