Can the issue be reproduced?
Yes

Issue
For some strange reason, after being hit I can instantly be hit again. That means that any melee mob will give me 5-10 hits per second, and dots will kill me in under a second (ic2 radiation, magma blocks, but not drowning or fire damage). It's reproducable with and without armor.

Thank you for the report, I will investigate the issue.

I managed to reproduce the issue in a new world as well as in a new and clean installation of the pack. I'm wondering how this hasn't been an issue for anyone else.

Me too O_O

Probably because most of them have 50+ hearts so they barely notice lol

(also may i just take this second to say - rip cyclic heart containers, i wouldve loved to automate you to get like... rose gold / golden hearts)

Fixed in next version :)
