Plantation does not complete

[Defendor]

This has happened to me two times now. I start off with a non-desert village, then I raise mountains and make it a desert village. When I get the plantation project, it says "City is in a desert" as one of the requirements, but it doesn't complete even though it is a desert village/city.

It is an incorrect sentence where "desert" should be "forest" :)
