When you are producing units, and the current spawn point gets full, it just stop producing units, even while all others spawn points in the city are free, on previous patch, it would automatically switch to a new one.
I have noticed it before, but i tought was an isolated case to nomad unis like hunnic hords, cause they have some restictions on spawn due to not mixing with normal units, but it happens with any unit.


I was playing a game going full on unit cost reduction (mysceneans, astecs, germans, ottomans, civics and even my tenets), to just be limited to pump just one stack of units per turn, and getting a massive industry overflow, it kinda ruinned my whole strategy, even if i'm winning anyway cause AI is bad at war, and Chinese bombard is just OP
