So I was making a slime farm and I can't figure out why is this hopper minecart not picking any items from the magma blocks above. Here's an image of the same thing happening in my creative world:
I am not using any activator rail. It's just powered rails and regular rails under the magma blocks. I'm currently on 24w06a snapshot on Minecraft JAVA, if anyone wants to know.
Also, something interesting is happening. If I break a block neighboring the one having items on it, the minecart picks the items. Here's an image:
I don't know the technicalities behind this. Please help.
