Insufficient funds show the wrong price

[ghost]

Describe the bug
Instead of showing the price for the next chunk it shows for the previous, for example, with the formula "c*10000" the first chunk costs 10000, the second 20000, but when you go claim the second one with 10000, the mod outputs that you need 10000 and if you have 20000 in your wallet, then it claims that chunk as it should.

To Reproduce
Steps to reproduce the behavior:

1. Set formula for claims to "c*10000"
2. Claim the first chunk for 10000
3. Claim the seconds chunk for 20000 without enough funds
4. Observe the mod requesting 10000 for the seconds claim, even though it will only take 20000 if you have them
