And just when i say something i proceed to lose 13 stam instead of gaining 27 D=

I don't know, i would recommend only gathering with really low amount of stamina, to minimize losses and, i don't know, maybe stamina stepping into negative might trigger the stamina oveflow.

But yeah, feels kinda unfair if there is people that can exploit it due to knowing the cause or luck. Even one win can bring more stamina than several losses. And seems like there's people that gets that stamina overflow constantly, who knows how. But i don't agree with punishing people, cause seems like nobody knows what triggers it, so it's not actively exploiting a bug, although it's unfair for those who don't get extra stamina.

EDIT: Just tried the reload thing, it went 101->101->104->101->101->101, so no exploit for me, but that behavior is weird as ****.
