I did my best fixing Resisto’s crippling immortal glitch, but it seems doesn’t entirely provide stability in some mentioned map packs. Maybe it’s related to health boost or healing outside the mod? I might look for a different method to replace this wonky code.
Again, this must be either addons’ or map packs’ custom stuff where they grant you max health item or upgrade. You might need to take it off via SLADE or give Revoltte a try while i’m solving this. Sorry for your inconvenience!
