I just pushed an update on the DNDI component to handle the issue reported on issue
I fixed the Encounter and AtWill duration and two other issues: empty links; monster from adventure vault that do not have level or xp.
But I found an error importing only 2 file (from all 4800 I had downloaded)

This guy does not load correctly via the plugin or the .monster file (actually the file is wrong on the Wizards site).
I can fix the import via browser, but I'm not sure this is the correct thing to do. The .monster file does import correctly but without the aura. You can fix this when importing.
