I find something curious here. Spider-Man is hitten for the second time by a Beyonder's scanwave in ASM 250 (11:4-13:1). Before he's attracted in Central Park to depart for Battleworld at the end of ASM 251, he appears in the end of ASM 250, in the beginning of ASM 251, in PPTSS 88 and 89. But in A 242, when the third scanwave hits, the Avengers run to Central Park immediatly after. I don't have FF 263 handy to check right now, but according to Mr Fantastic's chronology, he appears in FF 264, DAZZ 32, PPTSS 89 and TG 10 before M/SHSW 1.

If ASM 250-BTS and FF 263-BTS show the second Beyonder's scanwave, shouldn't they happen at the same time than UX 179-BTS and A 241-BTS, rather than UX 180-BTS and A 242-BTS ?
