[0.15.9][Twinsen] Decider works with output 1, but not input count

[dirtydan]

The decider combinator that outputs a red signal (input Green) does not output a red signal when set to "input count", but it does output when set to output "1" (when the conditions are true for both.)
The logic adds the 2 uranium types in the chest into a Green variable, and the decider combinator in question is deciding if the steel chest is full. (48 slots*100 items/stack=100 items)

[Anyone]

I encountered a similar issue, trying to output the amount of water (steam) via the decider combinator. When I did input count as output, it refused to give any output at all.

Input count copies the count of the red signal from the input signals, not from the condition. Since you have no red signal in the input, nothing is outputted.
