I don’t even use food buffs, just hearty meal, so not that.
No gear change, not that.
Within the last 2 hours, I went for 14532hp to 13532hp with nothing changed.
I asked a company mate that also wears heavy armor, he looked and the response was holy crap, cause he lost 1k too. He went from 9k to 8k.
Asked faction, and a lot of people noticed the same thing.
It isn’t the loss of a lifestyle bonus, otherwise it would be a % not 1k for everyone regardless of their level and health, it also only seems to be affecting heavy armor users.
