Can confirm. Minecraft Username: @RealRichNixon Brief Description: Spawners on MN (in the mining world, at least) are not resulting in mobs being spawned. Instructions: 1. Place a mob spawner of a type that is bugged. 2. Notice that the mob spawner is empty, and has nothing inside of it. Notice that mobs do not spawn as intended. How many times did you recreate this?: Several spawners have resulted in this kind of behavior. I've also tested clients Fabric 1.20.6 and vanilla 1.21.1. Result: Spawner "cages" are empty with the mob type not able to be discerned. Mob spawners do not do what they are intended to do -- spawn mobs. Expected Result: Mobs should be spawning, and ideally, the mob should be spinning around in the spawner "cage". Evidence: Catch me in-game if you need more information.
