Character name: Bum
I followed my friend around a cave killing bats, we exited a cave entrance and it happened to be the wrong one. This was a cave on the edge of a river. My friend was placed directly infront of the cave door and i was placed to his side, unable to go back into the cave. I was unable to move further than a few centimetres in any direction, and i was standing upright with my weapons out walking as if i was not drowning at all. We were checking the map to see where we need to go, and suddenly, i died. Apparently despite having swimming OFF, and walking around like on land or shallow water on a Ledge (not even actually standing on water) i had taken 160 damage from asphyxiation and dropped dead. If i had known at the time i was drowning i would have tried to do something, like tp home or turn on swimming and go round my friend and back into the cave /further around the ledge onto land- however after looking at my own screenshots and thinking about it, i didn't actually have the time to teleport or the stamina to swim to land. In other words, i exited a cave and was dead no matter what.
It says that my pictures are too big to actually post so i put in the one that proves i had swimming off when i exited the cave and died. I turned it on and off after dying to test.
