Gregg,
The only time that message appears is when the following happens:
- The engine is really factory-reset, which changes its engine ID# to the factory default, which would equate to a DCS ID# of zero (if there was a DCS ID# of zero)
- Whe the engine is added, it's engine ID# is changed to something in the DCS ID# range of 1-99
- That's when the message would appear.
If the engine wasn't actually factory-reset, the engine would re-add at it's previous DCS ID#, and the message would not appear.
