EDIT: Interestingly, the tooltip appears to work correctly when the MRM 10 is fitted into CP-10-Q ST hardpoint, but NOT when it is fitted into the CT hardpoint. Can anyone reproduce this?
EDIT2: Other combinations like 2x MRM 30 + 2x MRM 10 or 2x MRM 30 + 1x MRM 20 also appear to generate ghost heat without showing the tooltip.
EDIT3: It would appear that either the most numerous launcher present, or the type with the highest ghost heat cap is used in the mechlab. The interface won't warn about ghost heat when mixing two MRM 20s with a MRM 30, but will pop up the warning when you add a fourth launcher of any type.
