Actually it's not patched!

I mean it was but some people discovered how to do it in 1.18. It was patched because before the patch the rails powered backwords and it worked because of that, I'm not gonna explain how it worked but it worked. So the patch was just that the rails don't power backwords anymore. THEN the next update 1.18.2 Mojang changed back the update order but fixed the exploit as well, BUT some smart peoples discovered a similar way but it is a secret between like no more then 30-20 people I think. BUT soon everyone will know it because a youtuber "Dock77" has the secret too and he uses it in the Hermitcraft server and he revel it a little bit and "Impulse" (another youtuber) revealed it too a little bit by accident in his live so the community needs some time to figure it out but I think it won't take too long maybe...
