Repeater behave strange with 1 tick pulses. It seems the length of the redstone wire is important when trying to sustain a short pulse.
I created 3 parallel rows of repeaters, with 1, 2 and 3 repeaters. They get a 1-tick impuls.
What I expected to happen was...:
It should output a 3 tick pulse.
What actually happened was...:
Sometimes it created two 1 tick pulses.
Steps to Reproduce:
In the pictures are three variations of the wiring.
I made a 1-tick pulse generator, wired it into the repeaters and then into a long row of repeaters to show the pulse length.
The repeaters are facing north, but direction didn't seem to cause changes.
The problem only occurs when wiring the input at the bottom of the 3 rows.
