Shelters require 1 herb to be eligible for homestead upgrades.
I regularly see 2+ herbs in “Storage” in my shelters, yet the UI is showing me I do not have enough herbs yet.
This is preventing me from being able to progress into a Tier 3 Town Center as I can’t achieve the 25 homestead requirement. I have 5 or so shelters all with all criteria met including herbs in storage and indefinitely await upgrades to Homesteads.
In addition to Auto Upgrade, the most frequent reason for my Shelters not upgrading when Desirability and Herb requirements are met is not having 2 kinds of Food available to them. That early, I usually don’t have farms set up yet, so there is no bread, vegetables or root vegetables, and Food is almost all meat or smoked meat (or fish, it’s all considered the same) and Greens, and even if you have all of that in Storage, if the Grocer hasn’t stocked a variety in the Market, the Shelter will show Unavailable for Food. Just a suggestion: it’s always the first thing I check now when residences aren’t upgrading.
Yes, it’s strange atm that we have a button for that option, but it doesn’t work. Also what is strange is that the herb icon stays grey even when you have herbs in a house; it ought to go green like the others methinks, but it doesn’t.
