I tested, but couldn't replicate it. In the contrary, I has the opposite, no flag when it should have been a flag. I check my setup and found some interesting "issues".
Anyway, I fixed it now for the 2.0.4 update. I think might have been some changes in the sim about the gyros in the last updates.
Keep in mind that needs electric power from the inverter and flags will go out when the gyros are aligned.
