I've noticed that my airships actually fly better after the update, as the hovers now cause them to fall slower and not bounce along the ground.
The broken angular drag is causing very serious issues though.
Maybe they simply made them dynamically change their thrust/lift force, which, ironically enough, the description of the Zero G Plate specifically says that it can't be turned off, which likely means it is always at full power.
Yeah, well, I think the new hover plate stabilisation code will mean that their force should vary dynamically, depending on the motion of the tech. So different forces may be exerted, even when the ground is at the same distance from them, depending upon if they are in upwards or downwards motion, etc.
But the max force, when you have a (hub) wheel right adjacent to them, appears to be the same, in a stead state pose, at least.
