Hi,
We've pushed a couple of fixes since the main 1.1 update. There are some tweaks to improve AI getting stuck in some scenarios, but main issues addressed are:
Fixing the bug that caused a lap time of zero seconds to be recorded when a challenge is issued in a specific circumstance
Addressed the default resolution bug that was affecting some Linux users - this seems to be a Unity issue but our fix should hopefully prevent it happening.
Merry Christmas all!
Seasons Greetings,
Super Smashing Great Games
