After this mornings update 6-4-19 I can no longer add buildings to my Garrison. I have brought the book again and the general chat said I already learned the plans yet it will not allow me to drag a building onto any of the plots medium or small, empty or replacing existing building.
I too have encountered this on a few alts with no correlation to each other in terms of trying to replicate this problem. It comes and goes randomly for me.
I just had a bug with garrison. I brought all the blueprints a few days ago and when I looked it show I knew them. I log on today and it shows I do not know them. I look in to upgrade a building and it says you need the blueprint but I already know the blueprint.
I got this too after doing a realm/faction change.
Still happening and it really bothers me I cant level up a barn on my tailor.
This is still happening, blizzard. Completely disabled all addons, re-purchased the blueprints book (it said I already knew all the blueprints) and even bought level 2. Still cannot change out any of the plots.
I’m facing the same bug too. First the hearthstone, now this.
