Was the furnace on when it happened ?

Don´t know. Was not on the server. Only noticed that in console.

ok and do you have any other furnace plugins running?

Changed Status from Pending to Work in Progress

Changed Fixed In to Next Version

I have this issue to. It happens when someone puts just wood in the furnace and then clicks Run Splitter. It puts the players wood back into the players inventory and then throws that error into the console. The function is fine as I like it moving the wood back into the inventory if the player doesn't provide any ore to split with it, but maybe just get rid of the error spam and you're good   I don't notice any function issues when the error pops up. 

I get this error message when the furnace sees a partially cooked item if you try to use the splitter again after putting wood in it the error message continues and your wood disappears it does not go back into inventory. there seems to be an issue with amount of wood and the cook time desyncing or the plugin not properly placing the correct amount. If you speed up any of the cook times this issues increases. Not sure how this is happening but I do notice it definitely happens when the furnace thinks an item is partially cooked I get this message even when I just killed a pig and place the item in the furnace it reads it sometimes not all the time as partially cooked for some reason. The wood being taken is definitely not returned to my inventory it just vanishes.

Long time but just found the reason. The message appears when i use plugin UItemSort to fill the oven and than split it.
