did you get it figured out yet? Adhesion is bad there, maybe you can move it to a different place in on the bed in the slicer? did you try giving your bed a good dish soap wash and then wipe it with alcohol?
or add a 10 level skirt to trap more heat?
I have heard of people using painting tape to stick it to the bed when doing long prints that start coming up like that but that is lame
if thats an endor, do you have a glass sheet you can try printing on?
get a box of the alcohol prep wipes, they wont leave residue and you can one and done them while taking away the almost invisible film that will build up after a few uses
