When spawn_fix var is 1 will spawn the player a little up in all non RA2 maps. If you do in the middle of a game, you must restart the map to take effect.
The only way to know if a map was from RA2 or not was search for the "arena" substring at the MapString. But this left a chance that you have a map called something with "arena" in his name that aren't a RA2 map, then will not be possible to turn on spawn_fix on that map.
Then I created the var spawn_or (default = 0), which if have the value 1, will make the manipulation anyway, doesn't matter if is or not a RA2 map.
So if you have a map with "arena" in their name but is having problems, just turn the var spawn_or to 1 to do the correction.
I recommend you to create 2 lists of your maps, one with maps without problems, and another only with defective maps.
To know if a map is ok or not, start a DM match and look for their spawnpoints... if you can see them upside the floor, this is a good map. If not will need the spawn_fix on to fix the Siamese Twins bug.
