well there's something i found at pure... i had made a cutscene for someone. (zebra stallion)
and i used Screen->ComboT[ComboAt[Link->X,Link->Y]]=CT_SWARPA
which would turn it to a sensitive warp. he reported that this sent him, not to the screen he selected, but to the "win game" screen instead.
i didn't understand why, and i personally think it may be a bug, but im not sure.
and we are both using build 758
