Since changing the player name through Settings / Players doesn't take 
effect immediately, I suppose you used Edit / Edit position.

This indeed creates a new session starting from the position at hand + 
edits, clobbering the current session, and without warning. The first 
part may be unintuitive and the second is clearly bad.

Doing things differently depending on whether the editing is harmless 
(like changing a name) or not might be tricky

Clarifying what "Edit position" does is probably needed in any case, or 
redefinig what it should do if the current behaviour is inadequate.

For the problem at hand, being able to change the names in File / Match 
information could work as well.

This is almost what Settings / Players does.
