CONTRACTS FLAW

Very awesome game, iv been into hitman for years iv played all of them of course way too much, contracts especially but the part i despise is when i am about to shoot a ruddy swat guy in the HEAD boom headshot!! - not - the door closes on me automatic door closings!!! i hate that then they flood in and i cant finish the job in that take, its that door auto-close that is the flaw, really horrible idea why cant it be normal and stay open or shut when someone opens or shuts it? why does it have to close on its own its ridiculous how am i supposed to kill those stupid swats when the door slammed s hut on 47s nose and then when he opens it there all packed in there.. its seriously a boom of a flaw. the guns are great, levels great, everything is sooo cool about contracts except the doors that shut on yoU!!!! grrr so annoying... anyone sympathize?? I know There must be a "few" of u who had this prob to.
