Asobo 747-8 Intercontinental. MCDU EXEC button bug, can't save anything

Is this the same issue?:

Boeing 787 Autopilot Not Tracking

You’re right it should go out, but it doesn’t. There’s an issue with the stock 747 and 787 EXEC button. It’s easy to trigger it. Load into the aircraft, turn on power, press POS INIT, press GPS POS, press Set IRS POS, Press ROUTE, press PERF INIT and the EXEC light will just come on and stay on.

This cropped up after SU8 Beta. I would have sworn it was written up as a bug during that beta. I even searched all the beta archives on the forum along with the current bugs for the issue, but could only find my post and one other that mentioned it.
