 '''Pathfinding issue when user blocks passage with wall'''[[BR]]
 Case 1:[[BR]]
 1) Order some unit to move through narrow passage [[BR]]
 2) Order truck to build wall to block this passage before ordered units
 can reach it[[BR]]
 Error1: units ordered in 1) don't try find another passage to reach
 destination[[BR]]
 Error2: unit ordered in 1) swirling around axis non-stop like (if they
 think that all passages blocked - they should stop moving and wait
 orders)[[BR]]

 Case 2: [[BR]]
 1) Order some unit to move through narrow passage[[BR]]
 2) Order truck to build wall o block HALF of this pasage before ordered
 units can reach it[[BR]]

 They stuck[[BR]]

 note: in my last test when i blocked 75% of passage (3 tiles from 4) -
 units stucked, but when i blocked 2 from tiles - units passed
 passage[[BR]]
