corrupted MIZ files.

[Avalanche110]

Hello everyone.

I have an issue where random system failures occur in ANY Client aircraft. This issue occurs only in a particular MIZ file, which I suspected has become corrupt in some way. Other than the random system failures, the mission proceeds normally and theirs no other abnormality. I have checked and confirmed that the "random system failures" option is not selected.

I have tried this mission file on numerous versions of DCS OB and Stable. Their are no MODS installed.

I have been through the logs and not found anything out of the ordinary.

 

I am wondering if anyone has ever experienced this before, and if their is anyway to repair the MIZ file.

A huge amount of effort went into making it and I really don't want to start over.

 

Thanks

To Answer my own Question.

Yes!!!

 

Firstly, I can confirm that the Miz file had become corrupted, as opposed to a user setting causing problems.

To repair the .miz file, I converted it to a zip file and unpacked the contents.

Loaded the "mission" file into LDT (Notepad ++ equivalent)

I went through the endless lines of code that essentially make up the mission, over 100k in this case.

I found that the last 6000 lines of code make up the "system failure"____ System, this is embedded into all miz files regardless of options selected in ME.

 

I found that despite NEVER enabling any random system failures for any Aircraft, many of them were "Enabled"

I attempted to change these settings in the ME and see if it would update the Corrupted miz, however I noticed no change.

I created a new blank mission and saved the Miz file, unpacked it. Copied the uncorrupted Code that constituted the "system failures" into the existing mission miz file.

Re-compressed all files back into a .miz format.

 

I have found that the system failures no longer occur and the mission works as intended.. I have no Idea how this happened, I am just pleased it was able to be resolved.

Thanks for posting this, @Avalanche110. I've seen two other cases some days ago. It's as if some old DCS version was adding failures at random. I believe the issue is no more with current DCS version. However, if you bump on this issue again, please post here, and I'll be notified.

We have a persistent mission running on the server that all of a sudden started having random failures.
Looked into the .miz and yep, a lot of failures have 'true' behind them but they are off in the ME options.

I will dive into fixing them tomorrow but I just wanted to let you know.

Thanks for your feedback. I saw this issue twice in these forums. It's pretty rare and I still don't know how it's happening. If you have a lead, I'm all ears.
