[Q] Unexplained Events in Logs

[FifthDomain]

Good Evening

Quick question, I always have events in the logs that come from unknown problems, are these helpful to the Developers without a problem attached to them?

Some recent examples from the last few days:

Thanks for your time.

Similar question, so I will ask in this thread.

I have seen 2 fuse errors in the screen, however cannot provide saves to reproduce them.

Are they of any use?

[Dimitris]

They are useful, although exception logs are even more so.

I believe the OG issue has been fixed or not reproduced since?

[Nikel]

Sorry, what is the OG issue?

All the fuse errors found in B1776 while testing here.



Sonobuoys? fuse error, x20 and x400.

It happened in this 2 ACs scenario. I noticed something strange with the blue range of one of them and created the scenario to reproduce it, but instead got the fuse error. Not sure what I did to get it, just fly around.


Also appeared in Hail Mary. And can provide another scenario if needed.

Nicaragua Missile Crisis. Also x20 and x400.

Did not play it, just loaded and looking at the events in the editor, and running lua code. Related with this post, lua code to change the owner of a base.

I am not yet able to reproduce this. Is there perhaps a specific sequence of UI steps that consistently triggers this?

Can we get a series of steps that reliably triggers this?
