Laitly I have been getting this potal glitch where when I get out of a portal and walk a few steps it pulls me back into the portal, then I walk out of it again and it pulls me back in and so on... this happens 3-5 times before I am actually able to walk away. I'm not sure if this is because of the snapshot, but if anyone else is getting this glitch too, say so here.
I always get that, but normally at peak internet use times when my internet is bad (like now). It does this for about 5 mins if I use the spawn portal sometimes too. So yeah, you're not alone. I'm not sure if it's due to the snapshot or your internet though.
I am secretly a sheep. I just render as a human with a wooly blue jumper.
