When placing a storage bus on a mekanism creative tank, while also having some of the chemical in that creative tank inside your system and then trying to display the amount on a storage monitor, the server will crash due to the number overflowing and the monitor trying to display a negative value.

This was reported to AE2 but I was told the issue is coming from Applied Mekanistics due to allowing the tank to report MaxLong amount into the system. They suggested you clamp the value reported into the system to something more reasonable, MaxInt perhaps
