Here we go again! If your buildings take too many hours or even days to complete, this weekend you are in luck, because from Friday 23.03 01:00 to Monday 26.03 01:00 (Istanbul time) all building upgrades will take half the usual time to complete (or in other words, construction times will be 50% faster). Note that this will only apply to new orders, so existing building upgrades in progress will have to be canceled and restarted in order to take advantage of the event.
Have fun, and be sure not to miss it!
Your Tentlan Team
