Burnt woods never regrow in robot challenge

[Alastair]

As per the title - the burnt woods by the starting city in the current challenge never regrow in my game. Is this intended and part of the challenge? I don't have any DLC, and am not familiar with the mechanic, but searching online suggests that they are meant to grow back after about 6 turns.

Is it because I don't have the dlc so the forest regrowth mechanic isn't working for me? Currently just have 2 unusable titles (cannot build improvements, cut down or build districts, only 1 food yield) right next to the city which makes it a lot harder. But maybe that is all part of the challenge.

Thanks in advance for your replies.

It's bugged IMO
