We had a team of 6 on atheon hardmode, the praetorian killed the relic guy and the other two died right after. While that was happening us three were on the outside shooting atheon because he had a sliver of health left. All the sudden I hear them yell that they died and I ran jumped, tossed my solar grenade and we all died. As the timer counted down we watched atheon die from the solar grenade....but it didn't count.
