Not sure if it's a bug or not but conveyor belts aren't moving bombs for me. If this change was intentional, why? It was such a nice feature and really aided in farming.
EDIT: Nevermind it started working. Not sure why it was happening but changing the speed to the maximum setting seemed to fix it. Also like my post from a week or two ago, while editing them I noticed that the E button is now assigned to the camera as well instead of the furniture inventory.
