What's new in 0.9.1

Just a quick little update:

- Horsemen barracks are no longer invisible.

- Spanish translation updated to the latest version (thanks, Joaquin!).

- Forgot to say in the previous update: since fletcher's workshop became 4x4
instead of 3x3 it disappears when you load a game from 0.8.7 or earlier. Make
sure to rebuild it.

- Saved games are compatible with previous versions.

Thank you for your support!
