Description
[http://sourceforge.net/p/ufoai/bugs/854 Item 854] imported from sourceforge.net tracker on 2013-01-28 18:38:45

Trunk 10533 - I started a new game, and when I sent the aircraft to the first mission, the game crash to desktop with no error messages at all (the mission is loaded and right after it the game crashes). Nothing in the log file, but attaching it anyway.

Win XP SP1
UFO: AI 2.2 trunk 10533

Revision 10544 should fix this. It works for me at least. Setting this to pending :)

Had the exact same problem, no quit messages or anything either so I used gdb as the wiki suggested and got the following results:

Found the cause, selActor->fieldSize seems to cause the trouble; after having replaced this with the value of ACTOR_SIZE_NORMAL (1) the game runs as expected and loads the first level without fail. Not sure how to actually properly fix this as I was intending to look through the code and learn how stuff works this afternoon, but this bug kept me busy wondering if my map compiling went bad.

That one is a persistent bug :) mattn fixed some more bad uses of Grid_Fall and i just found some more (Revision 10551).
Please try if the bug still occurs for you, but I could not reproduce it here (though that seems to not say much :().

Just updated to the latest revision (10551) and it seems to work now without the need to manually modify those values into 1 or something :). So far loaded my save game and started an Antarctica mission without issues. So seems fixed.

Perfect :)
I&#039;ll set this bug to pending just in case. It&#039;ll get closed in a week or so.
