I jumped off the cliff close to the cave entrance on one side and cliff on the other side.
I didn't have swimming enabled after jumping off the cliff, and couldn't move.
I wanted to enter the cave, so I enabled swimming. I started swimming, but I couldn't move an inch.
I tried getting out of the water and over the cliff, or turning off swimming again, but to no avail.
I was stuck in place, running out of stamina.
Eventually, my character drowned.
I know it's probably impossible to bring the character back, but I would like to ask of you to do so.
This is honestly a last ditch attempt to continue playing the game.
