We shouldn't have to get used to something that was previously a feature and now is not.
Also the reason it was changed (to allow the tab key to make menus more accessible) isn't even functional so it makes no sense to break it now.
Can confirm this for 1.14.2
had 16 villagers in boats on a server completely safe. flew a few chunks away and when i flew back 4 of them had disappeared
I don't understand what the issue is with reverting it until they can properly fix it. Right now enchanting is so unrewarding that it's better to afk fish farm for books than to use the enchantment table in its current state.
Just revert the change until the new system is properly working.
Arrow keys being assigned to navigating menus would definitely make more sense than spamming the tab key, moreso than tab being commonly bound as the inventory open/close button
This issue seems to have returned in 20w14a as shown here
Issue occurs both with horses and donkeys
