I am writing this to inform people at Mojang or sth that when I load in a random seed and start my normal survival world, I usually live in a village and I found out that in the 1.16.4 bedrock edition villagers start to despawn when I am in the world. 

Even if I am near them or like 1000 blocks away nothing works, even when I come back from a mining session villagers randomly disappear.
