--- Comment #3 from Rencer rencer@euromail.hu --- (In reply to Nikolay Sivov from comment #1)
What you mean everything installed is gone? Which settings are lost? Please describe exact steps to reproduce, using vanilla wine.
Links update is covered by bug 47971.
Sorry, maybe my english isn't good enough. I can't tell anything more than I already told you, so I quote myself:
"every single time ALL SETTINGS that I changed in winecfg are reset to default and everything I installed are "gone", Wine doesn't see anything after this. Like it is a freshly created wine prefix without any change or anything installed in it."
As Olivier F. R. Dieric (Thanks you!) pointed out, I think my bug might be related to that bug report he linked: https://bugs.winehq.org/show_bug.cgi?id=22974
P.S.: WOW! A decade passed since that bugreport created, and this bug is still in wine. Just, wow....
