From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Jake Potrebic Date: Mon, 1 Jan 2024 12:57:19 -0800 Subject: [PATCH] Correctly check if bucket dispenses will succeed for event Upstream incorrectly checks if the bucket place will succeed in order to fire the BlockDispenseEvent.
