• Extended Building Information – works, but shows nothing for the new DLC buildings
• Sub-Buildings Tabs Tabs positions are off on some of the new transport hubs.
• Tree LOD Fix – error popup on launch for some people

Solution 2:- Game Issue Fix

If it is a game issue, then there is not much you can do, unfortunately. With so much variety in the PC setups of players, the developers can’t actually test on all PCs. Thus, this issue is kind of inevitable. However, to make things easier for them to fix, you can go to the forum and fill out this bug report form.

You might not receive a reply after filling out the form since the developers get a lot of responses, and it is not humanly possible for them to reply to all of them. However, rest assured the QA team is working on the issues tirelessly to make sure players get a seamless experience.
