3317	CCD fetch failures need to be cached	Tristan Croll	Greg Couch	"{{{
The following bug report has been submitted:
Platform:        Linux-3.10.0-1062.9.1.el7.x86_64-x86_64-with-centos-7.7.1908-Core
ChimeraX Version: 1.0rc202005242323 (2020-05-24 23:23:37 UTC)
Description
Trying to make a membrane model big enough to embed a very large complex (for visualisation purposes only, not for simulation). Took a PDB file with a pre-equilibrated slab of 256 POPC lipids (all named by CHARMM conventions), tiled it out to 3x3, renumbered all the residues, deleted hydrogens and waters, and saved as mmCIF. Trying to load the result back into ChimeraX hangs it for many minutes (at least 15 minutes and counting so far).
