Didn't think dying to desync would be so sad :(

For the past few days I've been trying out hardcore for the first time. My first HC character died on the ledge at level 8 to that big totem. I felt fine because it was mine own fault. Totally stopped looking at my life globe and didn't see it dropping like a stone.

Today I got Templar to the exact same spot. The client desynced and I could no longer attack monsters. I got swarmed and died. Sniff.

What should I do next time this happens? Just log off?

Thanks. Wasn't sure what to do. I just spammed health flasks and then watched myself die. Doh!
