I'm doing something probably ridiculous: I'm filling a giant hole with chocolate.

In that endeavour I discovered that my hole wasn't filling up anymore. At that point, I had a bottomless supply.
When I disconnect the hose pully from the already existing chocolate it works just fine, which leads me to believe that the bottomless supply is causing my chocolate hole to not fill up.

i believe this is intended behaviour

If it is, it seems I will have to find a workaround for my chocolate hole
