I'm having really good luck following your guide and I'm about to start with Appendix B (creating additional supply drop config files):
http://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=450135306
I was thrown for a loop with the MP start during some testing of a quad stack supply drop. In the editor it worked great... when testing it in a MP game, I found that six supply containers landed. This took me a little time to figure out.

First I assumed that playing with supply drop spawn points... I had inadvertently saved two of the single container drops into my scenario file. Examining the .scn, the phantom two containers were not in the .scn file.

Then it dawned on me that there is a double stack supply drop that spawns at the same time a player spawns (or at least the first player).

Pretty please... (I'm begging)... is there a way to strip out these auto spawning supply drops from the mod? (I know this is a pre-existing feature of the game's MP Coop start)

These phantom drops distort an MP scenario... I think a significant aspect of the game is figuring out how to get established with limited amount of starting supplies.

Anyway, much appreciation if you're able to work this into the mod!
