What's the most annoying problem then? That's a new one. The old exception error happened every couple of hours or so (on mine anyway). You also say "a few more things" like it's a small thing - yes, there were small things like the speedo, but there was also a big one - GTA3 support. Obviously if you don't have / don't like GTA3, it's not much use, but nevertheless, it's still a major feature that the team devoted a lot of time to (and hence less time to polishing the mod).
And of course, yes, the problems will be fixed, obviously.
