Captured+Annexed CS can't build WW

[TakenItEasy]

Late in Immortal I took a big gamble to try for my first culture win at this level.

I captured CS Rio De Janeiro specifically to build Neuschwanstein Castle and Sydney Opera House. Mountain 2 tiles away is Mt. Sinai. After waiting for it's pop to settle down, I annexed but couldn't see Neuschwanstein in the build list. Note that 5 CSs were still requesting it so it probably wasn't a bug with the global politics report.

I'm certain I've used a NW mountain for either observatory or Neuschwanstein before.

I could see that if a captured CS built a WW then was later liberated by another civ. it would cause a pretty awkward dilemma:
City State with WW?
Put WW back on the build list?
Delete WW until CS is captured again? (box of cracker jacks)
How to report WW in global politics window?

I could understand how not allowing any CS to create WWs could be deliberate but I couldn't find anything in the civilopedia on it.

It's a real shame too. This game was my best civ at Immortal and this bug? managed to trash it in just a few turns

I can't load your save game since I don't have the required mods. However, one requirement for building Neuschwanstein is that the mountain tile be inside your territory. Is that condition met in your game?

Yes, it's inside my borders.

Apparantly it's a bug when Neuschwanstein combined with a NW mountain.

Still curious about WWs in city-states though.

Capture a CS. Build a WW. Another player liberates CS. What happens to the WW?
