missions created in DCS 2.7+ occasionally render AN/ASN-41 navigation computer inoperable

[callmepartario]

Describe the bug
Newly created missions in 2.7's mission editor render the navigation computer inoperable.

If you load a mission created in 2.6, loading it in 2.7 has everything working just fine.

Additionally re-saving it to 2.7's mission format (including making cloud changes) does not appear to cause this breakage (in the develop branch, the quick-start missions are all updated and are not showing this behavior).

Thanks to SPINEG, HawkMoon and others in the discord for helping reproduce a few things here. Any additional testing or reproduction would still be welcome!

Software Information (please complete the following information):

• DCS Version: [e.g. DCS 2.7 Open Beta]
• A-4E Version [e.g. v2.0.0 beta 3 (could be happening on older versions, have not tested)]

Thanks callmepartario, please would you tell me where is the issue tracker ? I am trying to attach the miz file here

for example.

In my case, the navigation system is inactive and cannot be programmed either. You can hear the adjustment "clips" but the indicators remain at 0 and the system is inoperative.

It only works editing missions already created in 2.6

If you need more missions, information, etc ... about this error, I will be happy to share them with everyone.

thanks for your effort

fixed in 2.1.1!
