Issue: Mission Editor corrupting mission files(?)

[NoFear1979]

I edited one of my mission files because I found some conditions that were off. This is not the issue but what follows from my mission editing:

I saved the mission file per "save as" as I usually do. After this I wanted to close the editor. It then prompts again that I haven't saved recent changes (which is not true), and ask if I want to save changes. I press no since I have already done it. However this results in all content of the mission file being wiped out and the mission file at 0 kb and not recognizable by the editor to open.

Note that this was for saving on the same mission file.

I then tried to save as a new mission file, which didn't prompt when closing the editor if I wanted to save recent changes. However when I try to load this mission file under the mission section of the main menu, it states loading and nothing happens.

So there is something off with the mission editor it seems.

Sounds almost like something in the background is interfering with the files. Antivirus maybe?

Doubtful even when a possible scenario.

Some weeks back prior recent patch no such issues.

Hence my question.
