I just logged into an alt account of mine that I'm sure I had used on OSRS before. It didn't have much, probably about 50 combat and a few 100k, but I logged into it just now and it was on tutorial island. World 1, so not deadman.
Did I just imagine it, or is it actually possible that accounts can get sometimes get deleted? Whenever it's anyone else I usually think they just logged into the wrong account or a DMM world, but I could have sworn I'd played osrs on it... Very confused lol.
Oh well, I've got a fresh account without a normal non-email log in that I can make into some else now.
