[Chimera-users] exported as PDB, but structure is not the same upon reopening

[Eric Pettersen]

Hi Alex,
	AFAIK this should work.  Could you save a session just before you would write the PDB file and then use Help->Report a Bug and attach the session so I can investigate?  Thanks!

Upon reopening that very same pdb in Chimera, the bonds I made are gone (however, the ligands are in the position I placed them in). Curious to understand what I am doing incorrectly here.
