Problems with translating "%1$s %2$s mine %3$s"

[wl-zocker]

While translating, I stumbled across the string
"%1$s %2$s mine %3$s"
with the note
"* TRANSLATORS: %1$s = production site name, %2$s = production program name, %3$s = resource".
The string can be found in src/logic/production_program.cc:1129.

When I try to insert the %s parts according to the annotations, I get something like "Iron mine mines iron mine iron", which makes no sense.
Can someone explain how I have to understand it (or fix the string if it is wrong)? And where can I see this string in-game?

If you hover with your mouse over building, you get status messages once in a while. These strings are assembled together from a bunch of strings and are quite tricky to get right. I might have to revisit these strings again sometime to make sure they all work.

I translated this particular string as "%1$s %2$s – mining %3$s" in my language - maybe this helps a bit.

I only get the hover texts "Failed work because ...", "Produced ..." and "Skipped work because ...", so some more information would be welcome (what are the circumstances for this particular string to appear?).
From what I understand, %2$s and "mine %3$s" do basically contain the same information and are therefore redundant. Or can you give me some strings that can appear instead of the placeholders where this is not the case?

I will have to research this. The code is quite complex.

Fixed in build19-rc1.
