Cannot convert enemy farms with villagers

Has anyone come across this since the last patch? I just played 2 games where I tried to work on some abandoned enemy farms with my villagers and it didn’t work. It always used to work fine to my knowledge. Can anyone else see if they can reproduce this? Has something changed with this mechanism in the game that I missed somehow?

Known bug since the Apr 10 patch.

Oh really? I had no idea. Thanks for letting me know.

Was this supposed to have gotten fixed in a recent patch? I just played another game where it happened again.
