I'm having trouble purchasing the last house upgrade from NPC Proventus Avenicci for Breezehome house in Whiterun. I have all the upgrades except the alchemy lab, which he no longer offers for sale.
I've killed the first dragon, become a thane, got a housekarl Lydia, cleared the barrow, and have the Whiterun homeowner's guidebook in my inventory. Have not started any stormcloak v imperial storylines, currently level 11 just finished Miraak's temple.
There are many threads on google (eg here on reddit or here on gaming.se) with similar problems, where the apparent solution is to make sure you talk to Proventus Avenicci during the day, when he's in the throne room. Not when he's in his bed or in on the Great Porch or whatever, at which point he doesn't offer upgrade dialogue options at all.
My problem is something different. I'm definitely speaking to him in the throne room. And he's definitely offering the "upgrade your home" dialogue. It's just that the only subdialogue is "never mind". There is no "alchemy lab" option.
Is there a thing where you can't have all the upgrades? Maybe getting the child's bedroom locks out the alchemy lab?
Earlier when I was purchasing upgrades, I clicked on the alchemy lab but didn't have enough gold, so he didn't sell it to me. I wonder if trying to buy it somehow glitched the NPC dialogue into removing that option without actually adding the lab.
I'm on console, so entering commands is not an option. Is there any other way to reset the dialogue/house upgrade options? Will it come back over time? Does anyone else take over this options? Would killing the NPC somehow help? Any way at all to reset the configuration of the Breezehome house? Any tips would be appreciated. Very much hope to find a solution isn't "load an old save and redo most of the dungeon and two dragons and several grindy battles". Thanks in advance.
