The game is so buggy that instead of fixing it they should just remake it.

The Most Frequent Glitch that i enCountered waz.. the RoofTops wouldn't Load someTimez when uzing Fast Lifts.. Glitching Arno inside the Building with inVizible Wallz and eventually to DisConnection.. the Workaround i Found to this waz to Quickly Fast Travel to any Location to Save Time..

This is by far one of the most broken games I have ever played.
