Hey @ciske! Welcome to the forums! Sorry to hear you are running into this situation. To take a closer look at what is going on, could you share a screenshot of what is happening?

Hello @jkuiuyiyutr thank you for getting in touch with us.

We've had a few reports of players having issues when building certain mines.

Can I just check, have you updated the game to the 14.2 game update? Are you using any mods with the game, if so could you please uninstall them?

If you have checked the above two steps, are you able to upload a video clip showing you are unable to build the lumberjack building or the coal mine, so we can take a look?
