It looks like Sensible Entrance Points doesn't work correctly on BGT. The logs don't show any errors, yet none of the BG1 maps have their entrance points changed at all - The alteration to the Radiant Heart in BG2 is fine, though.
I also think BGT changes some of them anyway; The fishing village north of the FAI and zombie farm are already changed, and for some reason I always end up getting the east entrance point for the lighthouse and shipwreck maps, no matter what I do. The only thing left is the Beregost-Smithy entrance point, which clearly doesn't work.
