Redstone repeater bug
Ok so i was trying to figure out how do make a redstone lava trap so at one point the redstone dust fizzled out so i incorporated some repeaters. There was a lot of redstone dust involved. So i put a repeater down i pulled the leaver on a block the pistons extended but then they stayed extended and the redstone repeater stayed lit. also the redstone stayed lit
How to reproduce:
- Place 1 redstone dust.
- Place a redstone block on top of it.
- Put a 5x5 square of redstone dust
- On the 2nd row in, put a repeater.
- All the redstone will light up...
- Destroy the redstone block...
Expected result:
The redstone repeater and dust will stay lit up.

Repeaters will put out a signal when they receive a signal, even if the signal received is from itself.
This is working as intended.


You have a repeater, The output of the repeater loops to the input, and the circuit is powered by a redstone block.
You remove the redstone block.
The repeater still outputs power because it is receiving power (from itself)
This is what repeaters do, they repeat a received signal, even if the signal is from itself.
Your repro steps are a little confusing. Could you upload a screenshot of the contraption?
i get it now. so the repeater recieves power from the power source sorry in the picture i didnt screenshot the block with a button on . so then the repeater emits power through its other side then it goes back in so yes it is powering itself
