If when reading from the database it notices 2 instances of the UI name, it will notify the user of all the ZIP files that contain the UI name and asks them to consult the build creator for the correct pack.
What I mean is, does it algorithmically figure out which pack to use? (it should)
Pack X contains brick A and B, pack Y only contains brick A. The saves uses both brick A and B. Does it correctly handle that?
