Changes between Initial Version and Version 1 of Ticket #4241, comment 3

initial	v1
1	1	When we don't hit the target at the expected location, if we hit a nearby unit (in a radius equal to 2 times the distance between the expected target position and the real target position).
2	2	- So, here we get many entities to check. (perhaps we can modify that).
3		- Then the bug comes from that we have inverted the check for doing the damage so we give damage to the first checked unit we didn't hit. See ~~http://trac.wildfiregames.com/attachment/ticket/1910/1910_nearbyUnits.diff~~
