My newest upgrade for Meade Hall has just recently finished after about 5 days. I went to finish the upgrade and I was met with the following message
I tried restarting the game but was met with the message yet again. As for the storage space, I still have just under 100 GB of storage remaining on my iPad. I can close out of the message without having to force quit the game and I can do everything else around Berk. It’s just Meade Hall that is affected.
