Had this before, today it happened again. Several people encountered it, while others could use the box without problems (player in picture is using it right there):
This seems to happen regularly, now also on Summit. You can see people standing at the box to resupply, but it's not there for everyone. It's not just invisble, it can't be used at all but blocks movement.
Thanks for pointing this out! I'll pass it on to the team!
