issues with character validity

[stevenac]

I'm running a 2e campaign with herolab for the first time. My players all bought various sources that they built their characters from, but I did not - thinking they would still be able to use them for their own characters in the campaign. When I started the session on herolab, everyone's character crashed. I have all the sources checked in the options for the campaign. What are we doing wrong? Do I need to own all the individual sources as well for the players to use them?
