What does this mean for the macOS version?

Can I apply this over all previous versions or do I need the intermediate patches, too?

That is a known bug in the BFC version 1.01, too.

I dunno whether this has been fixed in 1.03 and can't test right now.

Can somebody describe how this game compares to playing TOAW4 at a similar scale?

Also, what language is the game coded in?

c#.

So a Macintosh port should be our first demand [:D]
