Industrial Electrolyzers, Blast Furnaces, etc
when using these machines you need to ensure that get a 128EU/t feed. This means you either need to give them a dedicated MFE for each one, or step down an MFSU to 128EU/t if you want to power more than one from a block.
The mistake I made was to have some LV things powered (using a transformer) from the MFE which of course reduced the supply below 128EU/t for the industrial item on occasion. This causes it to lose your ingredients and also to glitch in a way that means you have to pick it up and put it down again.
