I am not sure whether this can be replicable, but today I've encountered a bug (stated on the title). I believe that renzy had a high ping and maybe this is why the player couldn't take my drop. I just want to make sure that this is caused by high ping, that's why I'm reporting this.
When renzy killed me, I placed a bounty on him and then I got chased by him and his friend. During the chase, I challenged him on a duel, after the first duel, I dropped a bag for him and after it landed, it didn't give him health and armour. The "DEBUG" details are in the video.
