Game crashes when I try to create a new team

[suddennonsense]

This crash occurs when I attempt to convert a team battle into a FFA. To replicate this bug:
1. Select a map that is preset to a team battle, such as Hexcake, Moritori, or Merkwuerdigliebe.
2. Attempt to assign the players to their own individual teams
3. When you attempt to create a new team, the game will instead crash and force close.

Unfortunately, the logs do not appear to record this event. This is only event I've managed to record from this crash, and I do not know if it is relevant:

How do you "attempt to create a new team"? I don't see any UI widget for that.

Do you have any addons installed?

[suddennonsense]

Let's look at Merkwuerdigliebe for example. It has three teams set up, and only three teams. If you try to move a player to teams 4-9, the game crashes, because it cannot create a new fourth team. Every map that is preset to a team battle has this problem.

The widget used to assign players to the teams can be found next to the widgets that set up their gold and income.

Edit: Also, I uninstalled all my addons because they clogged up the logs with their own problems. This problem can actually persist on addon maps.

How are you assigning a side to a 4th team? There are only 3 teams available in the drop down.

edit-
It seems to be controlled by disabling Use Map Settings. I can reproduce this now.
