In the 4x4 chests I've noticed that the void upgrade doesnt work in the drawer when it gets filled it just gets greyed out and unable to take the upgrade out even if I put like a level II upgrade in the drawer itll still be greyed out like its disabled. For 1.12.2 playing ftb revelations

Void upgrades do not work at all in 1.7.10. I setup an overflow system with a trash can instead
