I'm sure they'll add features to it to make it nicer to use, main concern for them right now is functionality. It work well once you get used to it.
They changed/added 'hover' when ships reach a certain distance from ground. It;s a new feature and is still a bit buggy - hence your experience 😆
As far as I'm aware the only way to leave QT is if the ship breaks or it another player 'interdicts' you. But that "Engines Critical" warning just means that the ship itself will drop out of QT due to engine heat, sao shouldn;t be an issue. The ship won;t overheat and blow up, as far as I'm aware at least 😋
Port Olisar has been laggy since the day it was created but doesn't seem to affect me much. It'll improve as the game gets optimised.
I'm really happy you've been trying it out Dave, we'll have to pressgang @GazzaGarratt and @Diddums 😎
