I got board and swam out to sea for 2 hours strait. Found an underwater cave and decided to swim into it. I hit my air limit on holding my breath and the character floated to the top of the underwater cave then hit the cealing of it and just kept glitch repeating the drowning animation. I could swim a little in between the animation but my health never went down any and I never died from drowning. Took me another 30 mins to swim outa that cave while glitching.
