Oxygen sorters and cryo tubes

TLDR - Cryo tubes are sucking oxygen out of conveyor systems downstream of sorter blocks.

I have O2/H2 generators on one side of a sorter. On both sides of the sorter I have oxygen tanks. With just that setup all oxygen tanks will fill. When I add any amount of cryo tubes to the side of the network downstream of the sorter in creative then any tanks on that side will not fill. Placing a cryo tube on the upstream side has no affect on any tanks.

In survival, a cryo tube that has not been fully constructed has no affect. A completed tube has no effect. As soon as a completed tube is occupied, even if it is then vacated, it starts preventing tanks from filling. Until being completely deconstructed the cryo tube will still prevent filling even if it's just a frame. If a tube is finished but not occupied then it has no affect. In creative the tubes cause the bug without ever being occupied.

> = sorter, T = tank, O2 = O2 gen, Co = cryo that has been occupied, Cn = cryo never occupied

[O2/T/C > T] All tanks will fill

[O2/T > Co/T] Only tanks on the left will fill

[O2/T > Cn/T] All tanks will fill

[O2/T > T] All tanks will fill
