Custom Data - Compiler error referencing community pack?

[Gozuja]

I'm attempting to do some fairly basic self-created entries for traits and the like so that I don't have to manually type them in as custom entries all the time.

When I go to test in the editor, however, I'm getting a message that Hero Lab was forced to stop compilation after the following errors were detected -- followed by a fairly enormous list of community pack tag groups not existing and whatnot.

I've attached a screenshot of the top portion -- am I doing something fundamentally wrong, do I have a scrummed data package, is this a known issue, etc.? Any help would be appreciated.

Known issue - this happens on occasion.
I think the reason is because the pack is so large. Once this happens, you can only exit and restart the editor. (Make sure you save) I can't remember if you have to restart HL from scratch, or if just the editor itself is enough.

Darn, yeah it makes me fully restart Hero Lab each time which makes it a real pain to do any incremental changes -- essentially as soon as I change anything it won't compile so I have to save and restart, then compile, then go see if the change worked as I needed it.
