Progress has continued to be good since the last patch, with a significant part of our efforts going towards straightening out the campaign, which is being tested and fixed up internally at the moment.
For now we have a decently sized patch for you with all sorts of fixes and improvements.


A beautifully detailed WIP project by Sean Black.

Pieces of the various campaign fixes and additions are making it into the sandbox too, with the new market screen taking shape and now having correct calculations for car sales (yes, in sandbox).
We expect the campaign to be part of one of the next larger patches!
