Notes
(0002410) Warmonger (administrator) 2012-05-07 17:34	Happened before, happens also now after my modifications to AI aimed at this bug. It's still quite rare, though.

(0002498) Tow (developer) 2012-05-19 00:42	Duplicate of 0000957. (Actually 0000957 is duplicate but what's the difference...) Should be fixed in r2692 / r2693.
