Now when all of the oxygen is full, it stops producing hydrogen.
At around 350 hydrogen, all o2 slots are filled with max stacks, it keeps trying to produce o2 then shuts off when there is no room to place it.
Before it would just keep cycling back and forth and max out hydrogen eventually.
It does appear to not be using any more fuel at least when the o2 is maxed out.
Is this an implemented feature with the current patch(es)?

Since when? In 5.0 it’s always filled up at 350 hydrogen.
