extra lines drawn in Line+H and Stick+H views after mutate, hydrogen in wrong position; crashes while mutating

In a design puzzle, using the "+H" views (Line+H, Line+polarH, Stick+H, Stick+polarH), one or more extra lines (or tubes) are drawn from a backbone atom to one of the sidechain atoms.
Also, the hydrogen on the nitrogen following the sidechain is in the wrong position, appearing on the same side of the backbone as the following oxygen atom. (Hard to make good sheets that way.)
This happens for all amino acids except glycine.
Switching to a different view option clears the extra lines. Even switching to a different "+H" view clears the lines. For example, if you switch from "stick+H", to "stick+polarH", the extra lines (tubes in this case) disappear. The lines do not reappear if you switch back to the original "+H" view.
Once the additional lines are cleared, they do not reappear for the same amino acid at the same segment. They do appear when mutating to a different amino acid at the same segment, and for mutating to the same amino acid at a different segment.
Clearing the extra lines causes the hydrogen atom on the following nitrogen to flip back to the correct side.
This problem is generally reproducible, but not 100%. During testing on using a Contest, mutating to valine produced two extra tubes with stick+H on at least two tests. When I retested with the current design puzzle, 1355, valine only had one extra tube in some cases, and in other cases looked normal except for the hydrogen atom position.
In testing this issue, the client crashed several times when mutating. This may be a separate issue. An unhandled exception appeared in log.txt, but no debug.txt was generated. In puzzle 1355, mutating to glycine seems to cause a crash somewhat reliably. I'll open a new feedback if needed after further testing, since it's not clear whether this is related to having a "+H" view.
