A minehut server I'm on has broken. We were using it to test nether builds. I made a portal and left the nether and the game turned into a slideshow, due to lag. For some reason, there were several thousand zombified piglins in the nether portal. We killed them using to commands and got rid of the drops with commands, but now, we cannot re-enter the nether, there is significant lag, commands no longer work, and I am stuck in one chunk, and fall through the world if I leave it. Additionally, Zombie Piglins keep appearing from nowhere, even though the portal is gone. Does anyone have any possible solutions, as we really do not want to lose this world.
Thanks!
