At our server something strange happened: In my ore progresssing (wardtrobe vai hopper to crusher via hopper to Efurnace). It produced enormous lags for about a minute and desrtroyd all ores, the chest was also full, but at the start it did produce iron...

Mostlikelx ores got progressed, but still why is it so lagging ?

this has nothing todo with #227, industrial neon furnace bug.
