As far as my memory serves, I remember infra jumps were true both if you bought or sold infra; e.g. you have 1,999.99 infra and your infra upkeep is, f.e., $200 per level. You buy one level of infra and it becomes $250. You sell one level of infra again and it reverts back to $200. If this is not the case - which I doubt, but still - [/I] then I am wrong and there's no bug whatsoever[/I].

Yesterday I had 14,999 infra. I don't remember the infra upkeep amount exactly, but it was something around $850. I get to 15,000 infra, and it becomes $895.00. Fine I guess, I'll just sell the extra level and revert back to the old upkeep. But no, now the upkeep is $894.94 at 14,999.09 infra - behaving as if I had more than 15k infra.

Am I wrong, or have the calcs gone haywire?

There is not a infra jump after 11999 until you get to 18999 infra.

Really? I was under the impression 15k was a jump and it was the final one.

As for the OP, why not buy over again and record the results to verify it?

I did that. And I sold the extra infra again; infra upkeep is still somewhere around $895. Actually, I was aware that there is an infra jump over 15k. This thread, section V. b., reports an infra jump between 14,999.99 and 15,000.00, and says nothing about 11,999 and 18,999. That's why I believe there's something wrong in my infrastructure upkeep.

Your nation appears to be at 15001.09 infra... so your upkeep is going to be higher.

Yes. I just tried to cross the 15k again and see if there were any difference. Which is not the case.

Try selling down 14998.99, it's possible the jump is at 14999 instead of 15000.

Tried that. No changes. As strange as it is, it seems like there's no infra jump at 15k.

I guess it's possible that the infra jump is very minimal so that nations don't have to lose money on their investments too quickly.

You recently jumped about 4K in NS up. That might also have to do something about it...

So before we proceed, tell us what the 4K NS jump was caused by

Actually, admin just recently stated that there was an infra jump at 25k infra.

But as to the infra jump at 15k infra, it is a fairly big purchase jump, but the upkeep isn't very big at all. Look at the purchase price next time you go above / below and see if there is any big swings there.

Mostly Infra. I was at 14ksomething infra when I spent some 300 million in buying around 1k infra.

According to my understanding of the jumps, plus your tech level, resources, and wonders you should go from about $891.78 per level daily upkeep at 14999.99 to 894.31 per level at 15k.

You'd have to sell about 700 infra or buy NPP to get down to $850.
