Error during import of seed mechanism from previous simulation

[cgrambow]

I'm trying to use the core of a previous RMG simulation as the seed mechanism for a new simulation and the edge from the previous simulation as a reaction library. The seed and edge from the previous simulation were saved by setting generateSeedEachIteration=True. I then import them in the new simulation using seedMechanisms = [<previous core>] and reactionLibraries = [<previous edge>] where I added <previous core> and <previous edge> to the database.

RMG starts off by loading files:

Loading kinetics library decyl_cyclohexane_021 from /data1/cgrambow/Code/RMG-database/input/kinetics/libraries/decyl_cyclohexane_021/reactions.py...
Loading kinetics library decyl_cyclohexane_021_edge from /data1/cgrambow/Code/RMG-database/input/kinetics/libraries/decyl_cyclohexane_021_edge/reactions.py...

Adding rate rules from training set in kinetics families...
Filling in rate rules in kinetics families by averaging...
Enabling diffusion-limited kinetics...
Setting solvent data for decylcyclohexane
Adding seed mechanism decyl_cyclohexane_021 to model core...

It then prints a bunch of messages like this:

where I omitted most of the messages as indicated by [...]. Finally, I get this error:

Somehow RMG can't load a family/library even though the previous model was generated using the same settings.

This particular issue is fixed by #1200.

However, there's another issue I've run into loading larger seeds that I haven't fixed yet.
