// WANNE: If this is defined, this fixes the bug, that soldiers do not
// climb on roofs anymore if ASTAR is disabled.
// The "Bug" was introduced in Revision 1534 (TileEngine\Buildings.cpp)
// Overhaul wanted to improve the climbing on buildings, but introduced this bug
// If the VANILLA_BUILDING_CLIMBING is not defined, it uses Overhaul code,
// where enemies do not climb on buildings!!

// PS: I did not looked in Overhaul's Building code was causes the problem.
// If someone has time to debug and fixes the problem, Overhaul's code should 
// be used -> Disable the define!
