I couldn't find any topic yet on the building-upgrades.
In the first half of this year, barracks and provisionshouse could be upgraded without any restrictions.
Players like fishslice and Acee still believed it was still the same. However some people were severely
hampered when this was suddenly altered without any announcement from BB.
If you decide to upgrade your barracks to level 5, you will be in for a nasty surprise.
You cannot recruit any unit for a full week!
Same for upgrading the provisionshouse to level 5.
Does BlueByte seriously believe we are pleased with the fact that we can't make
any settler or basket for a full week. Who will feed the fish and hunters in that week?
Several people proclaimed: Bluebyte makes a serious effort to make the game fully unplayable.
So i seriously recommend:
Keep barracks and provisionhouse operational during upgrades.
Fairly strange to change the rules of the games so drastically, hope that BlueByte takes up on this complaint quickly.
