Was playing Custom Game to test AIs Barclay and Tess. Added 2 AIs in Custom Game; chose those 2.
Started the game and chose “Barclay” as my Incorporation name (had expected Barclay and Tess to be unavailable).
It allowed me to play (and in fact used Barclay image for me). The game seemed to select the next available AI (IIRC it was “Orion”).
Tess was still one of the AIs.
So I guess the intent is not to stop a player from selecting the same AI as has already been specified in the Custom Game setting
but it seems it should at least warn the player the AI is changing. Minor, but still…
