Can you try placeing it in Worldbuilder?
You didn't ask me, but nevermind: orchards can be placed in world builder and then they are working normally. They just can't be build at all. When you put a worker on forest tile, there is no button for building orchard (regardless if there is apple/lemon/olive or not). When you put worker on tile without forest, orchard button appears, and if you order worker to build orchard, it only build forest in the tile, w/o orchard
