I have noticed that items traveling through water over ice (eg, in ice-bottomed aqueducts) despawn if there is not a player very close by. Has anyone else seen this issue, or does anyone know of a setting to repair it? It happens even if aggregate ticking is disabled, and having to use hoppers instead of aqueducts is prohibitively expensive in Survival. Thanks in advance. I'm afraid there's not much I can provide in the way of screenshots or videos to show the lack of items.
