During several missions played in coop with cabalmembers, one member was unable to see my avatar, although another member could. I was not even visible on the map for him. First I thought his computer was unable to render my relic assault armor, once I doffed it and used another armor, but he could not see me in that armor either. Donned the relic again, after that he could see me.

I am totally at a loss why that happened...
