Expected Behaviour: Generator should respect fuel slot's content, as the recipe is available in JEI for all fuel source usable (any wood, burnable fuel), and move away from the "Fuel Empty Status" once there's a valid fuel item in the slot and consume it.

Current behaviour: As per my images below, despite a link is on the Workbench, fuel isn't consumed despite activated as shown on the green colour on the top right. The status is stuck on Fuel Empty and refuses to accept any burnable item, nor is the workbench functioning as a result of no energy being generated.

Quick update - In Single player, the speed of which electric travels is fast enough it's not noticeable, but when tps is wavering, and in a server environment filled with other mods, any change such as electric, generators etc, switches that turns electric off, all of those changes takes a long time (up to 4-5 minutes) for the mod to detect the change.

So there's currently an issue in a server setting where the mod isn't checking any state change fast enough to reflect the block state and its functionalities

I also am having this same issue. I tried both light and dark generator and every type of fuel that can be placed. From coal and logs to buckets of lava.

probably related to using mixin to tick the block:

Please just register a normal block ticker like any other blockentity

Lets figure out the problem first

Experiencing this with Craftoria modpack, both generators not taking fuel (running on a server)
