“Some excellent news. The plane visibility bug that first appeared in version 3.0.4 has been fixed. As well, the stutters and hangs that a number of users have experienced since SquawkBox 3’s original release appear to also be resolved. They are a lot harder to reproduce though, so a small group of testers is testing the fix to confirm that it no longer occurs.
Both of these fixes will be rolled into the upcoming 3.0.5 patch release. After a bit more testing, the patch should be ready for public release.”
Be sure to update when it is released!
