I'm seeing the same thing.  It's kind of nice at first, but once you have 30,000 Gildar in the coffers and nothing to spend it on due to lack of resources...

I haven't been getting THAT much loot from battles and sites though.  My cities are really cranking out the Gildar for some reason...

Might be those 3 caravans per City I'm now taking advantage of.

If this is a COMMON midgame situation, I'd suggest toning down the ruins/battle loot Gildar slightly (sometimes an extra few hundred GP comes in handy), but would focus more on just how much Gildar well supported cities can crank out.

I'd suggest Level 1 Ruins in the 10 GP range, Level 2 Ruins in the 25 GP Range, Level 3 100ish GP, Level 4 250ish GP, and Level 5 in the 500-1000 GP range.  I'm seeing some 200+ GP hauls from level 2 ruins - that might be a bit much.  If I have to kill something sufficiently threatening for that 200 GP, though, that's a different matter.

As for battles, I haven't been paying that close of attention to the rewards, but think an extra 20-200 GP as a reward (with 200 GP meaning you just killed something huge, mean, and tough like an Uber Dragon or something) is probably about the right range.  Getting 150 GP for killing some low life Bandits might be a little much, in Game Balance terms.

As for the salted pork booty, it has come in handy for those deep exploration missions.  I don't think I have too much yet, and as long as the opponent is able to hurt my heroes so I have need of it, I think it's a great addition.  In pre 1.09n games, I could never justify buying it (too many other things to buy, like buildings for instance), so getting a little bit for free is nice.  Lowering the cost (especially on trade in) might not be a bad idea though, so if you are the Pork King, you won't instantly become the new Midas!

That being said, were they considering an upkeep cost for Champions?  I know there is upkeep for armies, and it would just make sense that some Champions would require Gildar upkeep.

I hit a situation in my last game (still 1.09n beta) where my adventuring/ruins tech was level 3.  My economy was running in the negative (-5 or so a turn), and I built a few markets to compensate.

However, I was really racking in the Gildar from ruins and monster battles.  I went from struggling with around a hundred or so Gildar to having 41,000+ in the coffers in a small number of turns.  The monster battles were 'reporting' a reasonable amount of gildar, as were the ruins reports, but the Gildar seems to be go up a LOT faster than the game messages indicated.

I did take out a couple of kingdoms as well, but they only showed a hundred Gildar or so on the Diplomacy screen before I waxed them.  So I don't think that was it.

I'd guess a glitch gildar reward or two stuffed my coffers.  If it continues to happen, I'll post my save game, but as this is already a reported problem, I'm sure they are on it already.

My game crashed, so I'll check my income generation when I get around to playing again, and post what it says currently.

Edit: Just reloaded: the Gildar mouseover at the top shows me growing at about 39.8 gildar a turn. I advanced a turn without taking any other actions, and my Gildar advanced appropriately, from 42,936 Gildar to 42,975.  so it's not the cities that are the problem.  Several Caravans are in play at this point, and it's Summer 183 in my game btw.

I've played a few more turns, and Gildar generation was stable/reasonable.  So I'm guessing that, as mentioned before, the Gildar glitch comes into play as loot from battles every now and then.  As quickly as the totals jump, and the fact that I'm usually battling monsters a LOT when this happens, it makes sense.  I've been watching for specific instances after my last post, but haven't seen any recently.  I'll post them up as they occur.
