After changing the size and restarting my game, the left panel has disappeared from the layout editor and the left panel sits at a different height to the right one.

Yea can confirm it fixes it, just ran a 4 hour mission, no crashes (apart from one related to Achilles RC) only your Zeus' need it fyi

@keenan.smith500 haha yea just a few... running a Zeus mission tonight with the new perf branch Dwarden released, seems to have fixed it in prelim testing.

Having similar issues with all 3 Zeus' in my unit, started the day LoW DLC came out.
