It happened to me twice, but it appears to be random. Might be related to a specific object/structure (currently near Polana).
1st occurance: To the edge of Polana from the south east (Factory / Orlovets).
2nd occurance: Inside supermarket, ran close to the freezer thingy and pressed the jump-button (v)
If I find a way to consistently reproduce the issue, I'll update the ticket.
