Incorrectly reports undefined constants

[rightbrace]

I have an entry file A, which requires B, C, and D. B and C use types from D, but they're always available since A requires them first. This all compiles fine, but crystallline is complaining about undefined constants referenced in B or C from D. What's weird is that it only starts complaining about that when I save B or C, if I save A (even without changes), its fine again. My shard.yml contains:

targets:
  shapes:
    main: src/A

where A is the appropriate filename.

Is this a bug, if not, is there something I can do to force crystalline to do whatever it does when I save A?
