Are you really going to put limits on Silos and such? Crafters need more than 25 Silos and Storehouses. The amount of items that need to be stored for Food production and other craftable items take many Silos and such. I tend to stock the Taverns constantly, others stock connies on New Trismus with disks, armor, tools, etc. Putting a limit on silos would have a drastic effect on the production of these items.
I have no idea why you are even contemplating this change.
