When using a hopper minecart in an automatic farm the minecart sometimes despawns if the chunks are unloaded, this can be quite annoying on a survival world as it requires you to use resources to make a new one every time it disappears.

I am experiencing the same issue on v1.21.71 (running on realms with the Better on Bedrock Mod, real source and king rye texture packs FWIW). I know this used to be an issue with minecarts that are moving, so I changed the design of my farms to all stationary minecarts and it is still happening.
