1065	Swap sidechain occasionally yields incorrect geometry	Tristan Croll	Tom Goddard	"If I load up 5f4y with added hydrogens (not sure if that's relevant), select the ""swapaa"" right mouse mode and start rapidly dragging up and down on residue /A:1593 (or any residue in a helix), the geometry will fairly quickly break. The amide hydrogen starts getting misplaced almost immediately (particularly on passing through proline - for some reason on alanine it disappears entirely) and the direction of the CA-CB bond starts varying more and more dramatically (often ending up pointing into the helix). Continuing to scrub in this manner will eventually trigger it to stop adding hydrogens at all. The serious deviations in sidechain geometry only *seem* to show up after many iterations (and so may not be a problem in most cases), but it does point to something funny happening."	defect	closed	major		Structure Editing		fixed						all	ChimeraX
