Crashing Multiplayer but not Singleplayer

[Snake]

Are there any common causes of a map crashing in multiplayer but not singleplayer? I don't have any objects that would immediately make me think it could crash in multiplayer but after running the map fine in singleplayer I'll start a server and it'll crash upon loading. Is it just because it's steam? Maybe .lua issue?

are you crashing or are the other people crashing?

Just me as soon as it loads in. It's very similar to SWBF Museum but that works on multiplayer.

Could it be too many vehicles? I probably have 20-30 on the map. Some placed and some spawned.
I do have the memory pool set for it but maybe multiplayer artificially lowers it?

I thought it was my "placed in ZE" units but after removing those it still crashes.

Ok so I removed the placed units as well as placed vehicles (except for some kaadus) and that solved the crashing. I suspect it was Sereja's Barge that I set as a type: "huge" for planning purposes but I got an sptest error for that. I haven't investigated that further. I also put my placed units back in the map after it started working again to see if that did it and it did indeed crash the map.
