Reproduction notes:

I used the save provided (but it probably is doable with a new campaign using multi client test mode) but provided in case: PermaDeathAlexDoorman2.zip
Start a server up
Start a campaign with the save (Or a new one and get money)
Hide some submarines from the list (IE. barsuk)
Join with a second client, the second client will still see the hidden submarines in the list on lobby
Join in round, the second client will also see barsuk purchasable in the submarines list (where the host will not).
Presumedly many or all of the submarines were "Hidden" at some point, yet the host could see them, not sure if theres a way to cause this (didn't try to check - time) but presumedly its from the same cause. could just be starting the server with a hidden list causes that and the host "Joining" it.

Not sure how the host was unable to purchase submarines, but there does appear to be a desync here with the submarine list(s) on joining clients unable to start purchase votes and the submarine hiding feature in general.

None-host client:

Tested against the latest winter update and file transfer fixes, and repro'd it successfully on both.

I joined mid round and failed to repro it, I rejoined after having a character spawn and then reproduced it. this could be the difference in my steps is having an existing character in the game that has spawned? otherwise im not sure of the reason its inconsistant.
