Upgrading UP

So, for context, I have this shiny new raw UP of 10k, and I am looking to the future.
Planning to get myself a bit bigger UP even, I mean, why not.

So I go to the page: research.php
..



Dinner, I'll add the actual problem to this post later, because it kinda sucks.
Cliffhanger!

yes, the cost does start increasing faster

I figured that.
My point is, that up to 10k UP, you used to be able to order multiple upgrades (even more as you could actually pay for) and then it'd give an error saying you don't have enough resources to pay for that upgrade (**insert how many Kw it takes**).

Now, when I enter 10.000 to see what massive amount of Kuwal I need to gather in order to grow my UP a bit more.. it buys 1 upgrade, and didn't give the "you don't have enough resources"-error.
So I tried buying 2 upgrades, and it paid and added just 1.

My guess is, that for some reason, UP upgrades are no longer possible in groups. If I have to click 10k times to get from raw 10k to 20k, then that sucks. (But if it is meant to be that way, I'll stop whining.) If however that is a bug, then I would love to see it fixed.



Um. I would understand if that was too fuzzily worded, Admin.

Not enough funds to continue with operation (11,003,000,000)
Not enough funds to continue with operation (199,979,960,000)
and

You upgraded your Unit production by 5 for 50,040,000.

Worked like a charm here.
Anyways what you think, might be a bug but isn't one, is that the code (for simplicity sake) never allows you to go from lets say 9500 to 10500, due to the change in formula.
It may suck but live with it, for now it's how it is.
It will automatically make you get the upgrades to 10,001 where the new formula kicks in, then you can buy normally until 20,001, etc.

anything else?

so the formula changes per 10k?

increase goes up, each 10k.

Understood, thank you for clarifying!
