When I enter the nether after a few minutes the time in the nether just stops, the particles don't move, the mobs don't move, the blocks don't drop. And it's like this with an ugly and bad gameplay, and this bug keeps going back and forth for a few minutes. this bug if I'm not mistaken has been since the last official version of 1.16 But I didn't report because I couldn't log into your bug site, but now that I can I'm reporting it, and I hope they fix it soon it would help me a lot not only me but many people who suffer With this bug.
