 I'm doing a bit of mapping with P2 at the moment and found a curious bug.

 Upload of a large relation failed because placeholder way -1979 wasn't
 found. Ok, that shouldn't happen.

 But hang on... I haven't created 1979 new objects. Indeed, if I abort and
 try and draw a new way, it gives it id -180 or so.

 -1979 is definitely in the relation; the Members view shows that.
 Curiously, if I try and sort the DataGrid (by clicking on a column
 heading), I get an error:


 {{{
 TypeError: Error #1009: Cannot access a property or method of a null
 object reference.

 }}}

 (No such error with the non-broken relations.)
