Version 4.0.2.
Problem:
The single energy pulser action appears to work incorrectly and somewhat inconsistently.

Expected behaviour:
The expected behaviour is that the single energy pulser will e.g. extract one item from a chest every time the trigger event occurs.

Result:
Setting it to activate a singe energy pulse to extract from a chest activated by a button usually extracts one item every second time the button is pressed, even though the gate lights up every time.

Using a lever results in inconsistent behaviour (e.g sometimes every 2nd, or 3rd or 4th activation) but never appears to extract once per activation.

Appears to be fixed now, though rapid activation with a lever results in the missing pulses.
