We continue to investigate these issues. We're sure you can appreciate that some issues can take longer than others but we're still working to make sure you can have the best experience.
We can save any Workshop-item except the TMTK-items to our game folder. If we could save the TMTK ones also to our own hard-disc, the program doesn't need to download each of the TMTK-objects everytime again, when we start playing the game. I think, that could be one of the main problems.
