Hello!
Since the update, I experienced that my Stronghold Lab has lost a research slot. I have reached Lab Lv. 3 and yesterday I had 2 research slots available.
When logging in to the game now, there is only 1 research slot available.
Region: EUW
Server: Moonkeep
to make it easier for this problem to be addresed try to use the search function or the last list there multiple threads about this try to reply to this one:
opening up several threads about the same is slowing down the process
Sorry, I didn’t see that one here when I was browsing.
Thanks for the input
NP have a great day

Thank you for your answer. Yes, doing that did help me finish the tasks that had been completed, but is no help with starting new ones.
Happy to hear it is being worked on
