thank you for coming back to me.
I experience this with the Official version & the beta version of the launcher. But, as the lines are deleted by the server (if I understood right) & not the launcher, I guess this should make no difference.
I have a windows 10 pro system last build german and am not aware of doing fancy things - the exact build number I can tell in the evening when I am back home.
the launcher is installed on e:… (have to look at home for the exact path)
Have no antivirus except the windows tools
But after you validated my steps showing a different result, I guess I will set up a second windows system to cross check…
Will come back to you, after I have done.
Thank you for support!
