So ive been noticing this since Minecraft 1.17.30+ versions, and also 1.17.20+ that whenever i enter the nether, My bow disappears out of nowhere, i thought this was fixed from 1.17.30 but it still happens also in the latest version, it still happens, i dont know why  even tho i restart the game, and then i checked here on the bug tracker and searched for it about "bow disappearing when entering the nether" has no result so i made this report, hence maybe there is a report about this now or theres already one but its title wasnt like that then, so sorry in Advance if i made a duplicate of it. i made this report so if theres really nothing then hopefully it will get fixed in minecraft 1.17.44 or something. Thankyouu
