Hotloop Temperature Freeze and Engine Output Freeze

[Veilivel]

Did some testing tonight. It definitely seems like its tied to shutting off the purge valve pumps. Engine locked up every time I shut them off, but worked fine whenever I didn't mess with the pump settings at all.

Thanks, I remember you mentioning it over the radio one round, and it's consistent with what I've seen.  I'm curious why it happens.
