cT returning to old snapshot, removing tabs, time, drawing, indicators

I have completely …and … behaviour of cT desktop, both Win/Mac

When I close cT and restart it after longer period of time (over night) I lose everything, colours, tabs, drawings and system time.

cT is returning to some weird default/snapshot with no idea where it is stored. I lose everything, my open tabs, my drawings, time is reset to winter time, completely everything.

Old snapshot is loaded, with particular tabs opened at that time, old drawings at that time and old winter time.

I reinstalled the cT completely, deleted all directories created by cT, cAlgo and cTrader but cT is always returning to that snapshot.

When I close the app and immediately open it again, everything is ok, when I open it in the morning, everything is lost …

I'm considering switch back to … platform and writing …in app stores etc. I understand that system can have bug, but not this magnitude and I do not understand total lack of support and … from cT dev and maintenance
