Walls can't shoot on turn they are built (Spring patch)

[Leyrann]

See screenshot. Finished walls this turn (with normal production btw, not by chopping or something), barbarian is full health (so I didn't shoot already and then forgot), but I can't shoot.

Next turn, still can't shoot. Neither encampment nor city.

And yet another one. Would almost think they can't shoot over terrain anymore, but in another city I could shoot over a hills/rainforest tile.

Is that other city located on a hill?

Paris is not. However, as you can see, the swordsman isn't quite full health. I didn't think of it as of making the post, but in an earlier turn I could shoot him on that tile. Right now I got like 2 turns left until the encampment is finished, I'm hoping he moves to the holy site then, allowing me to shoot him twice for two turns in a row, assuming that I can actually shoot.
