Currently if you are loading an older savegame, you may be spammed with a large
number of warnings and errors (see bug516). This is very annoying, as you have
to keep clicking, and clicking, and clicking.


What is requested here is something like the following when there are errors in
loading the game:

A) Continue loading, show errors (current behavior)

B) Continue loading, suppress errors (this would suppress further popups) 

C) Abort savegame loading

Both B and C have not been implemented, and implementation of either would be
acceptable, IMHO.

I'm markings resolved as current savegame import benchmark will abort loading if
it thinks your savegame is corrupted.

At least if a data type differs it aborts the loading.
I also tested with another old savegame -- which I didn't played, various
complains about invalid virtual position and a print_trace() but yet no error
message ingame.

I think the current savegame benchmark solves this issue and I'm therefore
closing it. However if you find a incompatibility which will spam the player
still present, fell free to reopen this, open a new report, or even do a patch.
