City Revolt - questions and CTDs

[Makanyane]

Yep, you can still only have 4 ACTIVE building conditioned lines in the building or it CTD's when you click it, even with hidden view thing.

Which is actually plenty for me - we have some units that are additions for specific regions but base units aren't excluded by region so I can just pick one of the base units per barracks level - hence don't actually need more than one active line per building unless I get concerned about lack of variety being produced from unrepaired barracks... , have actually got the minimum amount in now to cover all factions / levels and seems fine so far

Active line changes when next barracks is built but so long as you remember to exclude the other barracks levels you don't get multiple lines. If you've got regional units that don't overlap you could just have one unit, per region, per faction, per barracks level, which would again only give you one active line at a time. I think you're only going to get into trouble if your regional areas (or other conditions) overlap so any one city could get more than 4 of the conditioned units active in the building when its triggered by any particular barracks level.
And I wish you luck figuring that one out
