When Lava Buckets are used in forge controllers as fuel, they consume the whole bucket instead of leaving behind the bucket like the furnaces

Hi, can you provide more details?
For example what version of the mod are you using, and are you using any other mods?

Hi Noaaan, I have been trying to reproduce the bug but it doesn't seem to reoccur. My server has been a bit glitchy and have been trying to make it more stable, I highly apologise for the inconvenience. I will report again if I am able to reproduce it.
