Hi,
Let me tell you something that happened yesterday, as my ship was enchored near an island I just ended up exploring.
I was jumping on the ship deck, trying to attach a lantern on the mast, when suddently I found myself high above the word -without drinking any potion. Time to realize "look, I'm flying !", I was falling down, scratching on my ship, and stupidly diying.
Hopfully, my character spawned back in the same island, and I began to run for my life...
