Today I connected to EMC to see how things were doing here; I hadn't connected in years because my old PC couldn't handle Minecraft. Well, there is a huge quartz installation near the point I left a year ago or so that I presume my brother created using illegal mods (because the whole island is leveled and there are two gigantic skyscrapers). While exploring this monstrosity, I wandered into a split iron door like an idiot and got trapped inside. I can't break it since it's griefing, I can't vouch for permission since my brother is banned, and I can't kill myself and respawn. I'd be very thankful to get some kind of help. Thank you.
Just in case anyone else comes across this issue, I think if you revert your version of minecraft to an earlier one it should fix the door glitch, I had this problem on 1.13 but not on anything below that.
