      There is an inconsistency when it comes to item collection systems seen below. It would be great if this bug could be fixed since it has been around for such a long time. Every storage system I use is huge and clunky due to this bug. It just would be easier if the inconsistencies I am about to describe are fixed.

      The problem here is that these item collection systems require the use of directional placement, which means that it only works correctly facing a certain direction. The ONLY direction that works 100% correctly is the North. As you can see by the image below, the North has grindstones as the block to put an item between the ice and the blocks. Here, the items slide perfectly fine on the ice. The redstone block next to the hopper means that the North side will collect items correctly using this method of item collection.

      From there, things get weird. The East and South side function the same way in that they have to use chests in order to allow the items to slide on the ice while also being able to be collected by hoppers. So the limit here is that you have to use chests and you cannot use grindstones, honey blocks, anvils, and other <14 pixel wide blocks.

      The biggest problem and inconsistency occurs on the West side. On the west side, you can use any <16 pixel wide block to have the items slide on the ice while also allowing hoppers to pick the item up. However, as you can see, there is no redstone block next to this hopper. This is because for some strange reason that makes zero sense to everyone, this hopper will not pick up the items like the 3 other cardinal directions do. This inconsistency is the reason I am creating this bug report in the first place.

      So, feel free to try out this bug in Bedrock Edition. Build what I have below or something like it and play around with it. I'm very sure that professional mincecrafters who build giant farms and huge projects have probably experienced this bug once. This is a bug that should not exist, so please give this bug report some attention so we can help to make Minecraft a better game one bug at a time!

      Steps to Reproduce:

      1. Build a row of packed ice with a row of normal blocks directly next to each other.
      2. Put a chest at the beginning of the row of normal blocks.
      3. Place a hopper somewhere among the normal blocks.
      4. Make a water stream running one way down the ice.
      5. Throw an item so that it hits the chest and slides down the ice path.
      6. Repeat steps 1-5 in all cardinal directions (rotate the build).

      Observed Results:
      When the items slide on the ice, they get picked up by hoppers unless the item is thrown onto the west side of a chest.

      Expected Results:
      No matter which direction the item is being thrown from, the hoppers should pick up the items.
