Hi, love the mod.
Couldn't find anything in the thread about this possible conflict, using mod version 1.2.0 on KSP 1.2.2
Just had my first malfunction, LV-909 Terrier engine (just a malfunction, not critical failure). Now a Kerbal is stuck in orbit with only 16 days of Oxygen left. He's a pilot, not an engineer, and I need 13 days to upgrade the Astronaut Complex to allow spacewalks anyway. Great stuff. Time for an epic rescue.
Only issue is, when I go to the vessel and test it out, the engine still works fine - produces thrust, consumes fuel. It's highlighted in yellow, in the part details it says 'engine: malfunction', but everything still works.
I've done a bit of testing and narrowed down the problem to RealPlumes - I've removed the base mod, the stock configs, and smokescreen, and everything seems to work as intended now.
Just thought I'd let people know in case similar problems crop up.
