relocating question

hi all
i have just seen a player who had just relocated and had been hit, the bases he had used to attack a player with relocate again to another sector.

one of our players has BRs of the attacks on 2 bases of this player to prove he had been in the first sector he jumped too, he was on a 2d timer in the first sector, this happened on T13, i am online there at the moment.
am i missing some sort of glitch here?
