If you have full item inventory and attempt to pick-up a plague ichor, all of your teammates will recieve it but, because your inventory is full, you will not - and the plague ichor will remain on the ground. You can then repeat this process as much as you like, allowing your teammates to gain infinite plague ichor.
Hi guys, I was playing with a friend and we came across a glitch duplicating plague ichor.
We were doing a red bounty. I died and I had no more room in my item inventory meanwhile my friend killed the boss. Then I tried to put the plague ichor in my inventory but my friend received plague ichors instead of me. I could spam the gather button without the plague ichor disappearing since I didn’t have any room for it.
Here is a screen of my friend having an insane amount of plague ichor resulting this glitch.
