Possible worker bug?

[Bert-Jan]

After I research agriculture my workers gain the ability to build farms but they also seem to lose that ability after they've built one. Now the only thing my workers can do is build roads and chop forests. Am I missing something?

They shouldn't lose it.
Did you move to tile without irrigation/freshwater?

Save would be nice though

That's probably it because a seed farm can go where you don't have that but a farm cannot. And you can't string farm irrigation until later technology.

Probably lost the gold required to built one after building the first one. ^^
