Bomy life bug?
 

I was fighting with Pirate Crew and after killing 2 guys I only had one hit left before dying, so I run and pull out a bottle of purewater to heal (It heals completely for bomys). After that I go back to rox some more sox, but some guy runs up to me, hits me once, and I die, then I am reborn in heaven with full health except for one hit was taken out of me.

if the person lagged that hit you than there's your answer.
For some reason if the person(s) are laggy when you trigger an action like healing it doesn't respond for a second.So you could heal and they wouldn't get that for a second.
This happened A LOT on classic, and rarely on p2p.

thats sucks

when i was playing on classic, please dont laugh, i used a bomb on some grass and a gralat appeared, and i ran over it for about 5 seconds before i finally got it, just lag :D
