Can't build walls in Cassiterides

[Ebbingford]

Playing as Britonae.
As the title says, I can't build any kind of fortification in this region. They just don't appear in the list of buildable military options........
I also took the crop festival option and it hasn't been removed from the list of buiildings in the region. Other regions it gets removed OK.

There are more.......
Finnis Terrae, Olina, Cantium.......
Roman Camp is in the build list though, shouldn't this be special for Rome?

[Pocus]

yes, can you pass me the save please?

Send the file(s) to support@slitherine.co.uk, copy-paste the thread URL and title and mention this is for Pocus please.

DRUID HIDEOUTS IS THE ANSWER

Can't be placed inside a walled city, so if the Druid hideout is present, then no walls can be built......

Have sent you the save Pocus for the Roman Camps anyway.

Yeah, one less thing to check (was a bit slow on this one).

I found the issue with the Roman fort also, thanks.
