No Graftblood

Hi, i play in duo/trio and sometimes after the breach close or after a defense for Ailith or after Fortress i don't get any Graftblood. both of my mates got their graftblood, i'm the only one who don't have any graftblood.

thank for your answer/help.

Are your grafts already full of graftblood by any chance?

of course there not...
i saw a post on Reddit, some ppl have the same problem as me.

You probably need to investigate and suggest on the bug section then, if it is not a logical gameplay mechanic. If you are not doing anything differently than the other party members, then it does sound like a potential bug with grouping.
