I started on an island spawning in the lava block, I finally got out but was on fire now the whole island is covered in lava and I can reset it. the /newisland command never resets it the island stays as lava covered is there a way to fix this otherwise it's not playable for me.
Next time you're online, ask a friend or a mod to put a fire resistance potion on you then you can /home and fix the lava problem
