On Eichenwalde map, Ventures ult can go around corners and over air to hit you on the bridge outside 2nd point. You can see a Venture on the attacking side around the corner and defenders using line of sight to be around the corner hiding behind the bridge arches (not sure if that is what they are called - parts of the bridge that are higher up and stop you from falling off if you run into them). The ult goes right through LOS and essentially through the air (since there is a drop there) and continues onto the part of the bridge that should be blocked). The angle from where the ult originated should not be able to hit if you are not in LOS.
Other odd behavior which probably is not a bug, but should be considered one is Ventures Drill Dash (possibly Burrow - not 100% sure) ignoring shields. Really gives very little counter play for heroes that use their shields correctly.
