In my server log on my SMP I see this frequently spammed in the logs, it doesnt cause lag or crashes from what I can tell, however I would like to know if this is normal or a problem that needs to be fixed like the saplings in tubes + crystal chests bugs I had to fix a few days ago.
 
This is what is spammed about 15-20 times every so often.
 
[Server] WARNING API ERROR: ic2.core.block.machine.tileentity.TileEntityMacerator@13cace52 didn't implement demandsEnergy() properly, no energy from injectEnergy accepted although demandsEnergy() returned true.
 
Thank you for your time.
