caged dungeon spawners spawn once then quit spaning after new update. tested in spider and skelton and both ticked once then stopped. this is cruicial to maintain elytra with mending and makes most of the new update broke. id rather not rest the end evey day, kill the dragon, deal with shulkers just to have flight. this should have been tested before release seeing its importance to the game mechanice of flight. i play on a tu45 world so it is from last update. hopefully you guys can resolve this soon.
