Hi, I think I have found a bug, but I don't know it is from the game or from BUFFY. BTS version 3.19, BUFFY mod 3.19.003. Please open the save and look into city "05". There is a WB on the queue with some hammers on it that will start losing hammers soon if it is not the first thing in the queue. Now, there is a second WB on the queue with 0 hammers on it which is threatening to lose hammers soon too. If I start losing hammers on the first WB and then complete it and then put some hammers on the second WB and then put something else on the top of the queue, then the second WB starts losing hammers immediately, instead of starting losing hammers after a period of time (10 turns in normal speed) as it should. EDIT: I haven't attached the save here since it belongs to a competition that is not over yet, I will attach it on the 16th. In the meanwhile, I can send the save by email to any admin that is not playing that competition.
