So i was bored so i set up 2ms clicker to put MANY tnt minecarts on the rail. The game started to lag and i think i broke it... The mobs weren't moving, redstone and anything else didn't work and i couldn't push the minecarts to let them detonate. The world is literally unplayable. Is there a fix for this problem? i tried setting up a mouse 1 clicker and destroying the minecarts but of course it didn't work. Is that possible to delete some chunks from the world?
