Haha I may need to fix that bug but I wouldn't mind someone having the item, that's why I gave it a debuff. It's kind of an easter-egg but I haven't intentionally left anyways to get the item tbh!
Also those events should still trigger your equipped medkit, maybe you took more damage than your medkit can heal? If not that, then perhaps there's a bug with it. Equipped medkits don't work in instances where Death is considered a potential option, like the EFIM injector.
