Hi,
I'm new on the forum but have been using the 5e generator for a while now. I just downloaded the latest version (2,22) and imported a character that was made with the 2,0 Beta and noticed that not all data was being imported, not sure if this has been raised before? Anyway after importing the character I noticed a couple of fields hadn't come through on the import. Don't know if the character type has any affect on this but my character is a half-orc barbarian. For now I have noticed only two areas where this import didn't fully work: the field subclass -> primal path did not import & for the Attacks only the 1st attack/weapon was imported, all others (2 through 6) did not import.
What beta version were you using? There were some fairly significant internal changes between beta 1 and beta 10 (or so) and the import function will not fully work with them and the current releases. You will probably have to manually re-enter that data.
