In puzzle 193, when recalling a memorized position (using ctrl-1 to 3 or Restore Very Best) the protein does not smoothly morph into that position. Instead, it just suddenly jumps to the recalled position, which is often oriented very differently.

This happens when the current and recalled position originanted from two different puzzle starts.

Why this is a problem: it is practically impossible to compare the two positions. One has to tag a segment using the "tab" key, reorient the new position manually etc.
