alright I will make guys to test with to see if they moved the click point on the BOD. It is possible. You playing on a default resolution meaning your computer its self has not been altered in the control panel. I had a computer where i actually changed the resolutions in the main screen once and this stuff was always a little off due to that. Although that would cause a lot of scripts to give you hell.
The only other thing I can think of is that you said it has already tried to get the bod before the backpack opens. WHen the backpack finally pops open, it becomes the main gump. this would cause the bod collection gump to not show in the EUO variables. If you are comfortable with trying a change before i get home tonight, you could simply try a wait 2s after the log in sub to let the backpack open fully before getting the bod. That was the only other issue that I thought it could be besides a gump size change. With .1 skill that should be the same size normal bod every time so I really doubt it is a gump size change.
It must be that the backpack is popping up or paperdoll as the log in process and taking over the bod collection gump. We will get the timing improved but it is awful weird to see these timing issues. I wonder if the last patch changed some of the timings to mess with folks.
