yes.
I thought the values in the second and third slot were accurate usually, but they don't appear to be.
However, the sum of all three slots still sums up to the requirements, so that's something.
If you can't add anymore of a given input, then you should be finished with that resource.
TLDR: don't let your resources decay, build the signpost immediately after adding new ones
that way, you don't waste resources and you never encounter this bug.
