I was trying to make a piston trapdoor (i am not the best at Redstone so it looks terrible) and i got the first side of the door to open with some pistons and a lever, but when i try to hook up the other side with more pistons it would work because i was using Redstone blocks and i think the quasi connectivity bug had to do with it.

I then tried to use Redstone torches and i put a Redstone torch on the side of a block with a block on top and Redstone dust going into the Redstone torch and it was powering and unpowering the torch and dust repeatedly, keep in mind that the dust is not powered, then after a bit it makes a burning sound and stops.

Every once and a while it does it again and when you block update either the torch or the dust it start flashing too.

I would like to add that even while i was typing this it was constantly going off at random ish intervals.
