Hi,
I'd like to get rid of the "old" Factorissimo 2 mod and replace it with this one. I am aware that I cannot copy & paste the factories and their contents. So I plan to empty all factory buildings, delete all factory buildings, change mods and then rebuild the factories with the old blueprints.
Question: do I really have to empty the old factories first or could I just delete them with their content? Emptying all of them would take ages...
