[B41] OnObjectLeftMouseButtonDown event first parameter (IsoObject) is not correctly updated.

[Tchernobill]

Context:
Game started, screen is centered on the player.
Mouse Cursor is placed on the top left of the screen (on a tree).
Left click => IsoObject (first parameter of the calback) is the tree the mouse is on.
Move to the top the character (and the screen) using keyboard control (no mouse movement).

 

Current (B41.50 & B41.53):
Left click => IsoObject is the same tree the mouse is not anymore on.

 

Expected:
Left click => IsoObject is the object the mouse is on.

 

Note: this may explain some strange behaviors when trying to place objects precisely during building process.
