Part Misalignment in Snap-to preview
As of version 1.11.1, parts often refuse to align in snap-to mode. Sometimes the misalignment is large. Sometimes it is ever-so-slightly off, and the small difference breaks the design. Alignment bugs(YouTube)
Part misalignment on placement
More often, the parts preview is shown as aligned, but the actual placement is off slightly and by random-seeming amounts.
Observation: the ship also “jumps” a tiny bit on placement, I have to imagine that this is linked with the placement bug.
Proper alignment is a prerequisite to having any controllable vessel, so let’s hope the bugfixes keep coming.
