A valid issue...
My guess is Beth will do what they always do, either patch it to make it work because its been broken or do... nothing.
Only that they will have to alter the perk. Perhaps allow it to bypass the damage bit for being over-encumbered.
Good point. I'm actually 1 point away from maxing this. Maybe I'll wait to see what happens first
It's also somewhat contradicting.
Strongback Rank 2 supports you to run when overweight. But in Survival, carrying too much will hurt your limbs.
So...
