Calculation fails due to missing metadata

[dgdekoning]

This occurs when a custom database uses activities/processes copied from a different database which itself is dependent on a third database

eg:

biosphere3 -> ecoinvent -> customdb

When attempting to run a calculation with processes from the customdb the activity browser recognizes it needs to add customdb and ecoinvent to the metadata, but misses that it also has to add biosphere3.

Workaround is to "manually" load the datasets into the metadata by double-clicking the relevant databases in the left panel.

Interestingly, the issue resolves itself once the user actually edits the copied activity. Just needs a little nudge apparently.
