Hi, sadly I didn’t find anyway to use the super factory limit not to reset…
I would encourage you not to use the cheat though as I see the cheat also affects other nations as seen here:
I could recommend a work around as follow:
use enable console command cheat > open the console command > type in research_on_icon_click
Then research all the industries tech, you can even use some exploit by researching both tech trees. This should give you the maximum building slots and other building bonus for every territory you have, examples:
Other than this you can simply enable the super production cheat (you only need to assign 1 factory for each slot) and u can get huge amount of equipment / ships / aircraft / tanks.
Or if you wish to use the console command you can use:
add_equipment xxxx aaaaaaaaaaa
x = number of equipment
a = name of equipment
example: add_equipment 1000 Panzer II Ausf. a
This will not work on ships though, try and play around with the console command and you can do wonders with them
