Not technically a bug, so I'll put it here.
I'd like to ask for removal of the feature that turns all slaves and workers to spawning items in base defense missions with random timers between 0 and 100 halfturns (Except Yeomen with 0 to 8 and gladiatrices with 0 to 30 halfturns), which then spawn "civilian" slaves.
It is impressive, it is logical, but it is a pain in the ass.
Specifically I am talking about cases when you have around 1000 slaves in a base and you are getting around 10 civvies spawned in every halfturn.
Alternatively, you could just raise the minimum timer (10 halfturns, perhaps?), so that there is a chance to complete a base defense mission before civilian turns get extremely long.
