We have a hotfix out that could prevent some players from activating the DLC in game. Please update your game files to the latest version.
Patch notes:
Fixed a crash on load of some older saves.
Fixed an issue with the in-game DLC selection that could show the DLC as enabled when it was not.

- Fixed: Moving a production building or storage building could prevent transporters and production workers from collecting resources from that production building.
