Network/restart bug allowed me to have 3 starting spots
Starting a game in Catan (4 player, first island) and it hung up during the round of picking (at least one player didn't see my 2nd pick), so I restarted. When I rejoined the game, it still had my 2 spots, but prompted me to pick a third! Which I did, and the game started with me having 3 spots and everyone else having 2.
[I was running the latest version through steam. And I know at least one player was on a device (android or ios).]
