Hey Tom,
Just to be clear ... do you anticipate this fixing the Nightlies for:

RogueResearch3 (50 Build Errors) ?
RogueResearch5 (50 Build Errors) ?
Dash14               (50 Build Errors) ?

I'm trying to focus my effort on what remains, and would hate to chase an
issue that you've already resolved!

- Wes
