Fluix mana pools and mana mirrors connected to them appear empty and looking at nbt of mirror shows negative mana amounts.
To reproduce, have at least 2 or 3 ME drives of 256k mana storage cells and then place a fluix mana pool.
Possible that this is due to 2bil int limit or something?
Sorry if this is fixed in 1.4.5 btw, unable to test it atm and not sure if it would have been fixed by accident viewing changelog
