Been playing on this world since January and have had the odd luck of always running out of hunger as I entered the end. But today I finally learned to look at my hunger bar as I entered and... I seen it deplete fast. So I recorded myself entering 5 more times (respawn point over the portal)

Upon entering the end hunger may suddenly lose 0-10+ points

Variables may be holding sprint, holding crouch, or being in water, as I was getting hungry while entering before the conduit was in place. (Video description has shift/control keys held in video documented)

Recorded footage - Youtube

Edit: Did it again in vanilla (no fabric) and it happened on 2 for 2 tests, the second one loosing 10 hunger points

Edit: Did it again in vanilla while server was also running vanilla with F3 stats showing https://youtu.be/3aZ7frexqTY

Same day: did not hold shift or control, and lost several points of hunger

Edit on 6/22: I have trimmed my world to 31,537 KB to share the environment where the bug occurs End portal location on google drive
