Teammates on Team 6 are not automatically placed near each other when the ‘Team Together’ option is enabled. This only affects players in Team 6. In Team 6, teammates will always be placed far away from each other, as if the ‘Teams Together’ setting was not enabled.
To reproduce the bug, go to main menu >> custom games >> create >> select a map (I chose Emerald Gardens) >> advanced options >> ensure that ‘Teams Together’ option is ‘on’ >> map information >> create >> fill remaining 11 slots with AI so that there are 2 players on each team >> ensure that only Team 1 to 6 are used (Team 1, Team 2, Team 3, Team 4, Team 5, Team 6) >> start

Expected result: Teammates on all teams are always automatically placed near each other
Actual result: Teammates on Teams 1 to 5 are always automatically placed near each other, but teammates on Team 6 are always placed far away from each other

Update:
as of 1.36 this is still in game. Teams are not starting together if there are more than 11 players. If you take an observer slot, and enter the game with 12 players, teams will be scattered across the map chaotically, even though “Team Together” setting is checked.

Update:
this is now fixed! World Editor → Scenario → Ally Priorities Properties → set High Priority to everyone who you want to start next to you, and low priority to the ones in the opposite side of the map. Sometimes even this doesn’t work though, but that is due to a defective map, such as Emerald Gardens, while most of other maps do work, and teams start together correctly.
