Something wierd wend down just now on the tick...
I had a whole lot of buildings set to complete, had just set draft to begin drafting again prior to the tick and on the tick soldiers did not draft, income did not increase, the in progress buildings that were all sposed to complete on the tick totally disappeared from the queue but are not in my current bullt list although they still count towards my total acres...
I am not the only person experiencing this as at least one kingdom mate is in the same boat with a heap of his buildings completing the same time as mine...
