1.12.2 Overflow Error Results in 0 RF/t Crystals with weird symbols

[Renno231]

There appears to be an overflow problem in which somehow the values for the crystals can become some weird symbol, and the total RF/t from the crystal defaults to 0. I'm unsure what the issue is as I have broken and replaced every machine involved. I've made an automated factory for deep resonance several times before, but this time I'm using rftools control. The main difference is that I'm moving the fluid from the infusing tank to the crystallizer tank using the multi-tank from rftools control. So far, I've made eight crystals, four of which have this overflow error that renders them useless.

This is probably already an issue somewhere, but I couldn't find anything related to overflow.
