When a redstone signal is fed through a block, and then (with both repeaters on) the initial repeater is switched off, the second repeater will go crazy and start looping on it's own, without any redstone signals. This clearly wasn't the case in 14w25b. I don't know if this is normal but if it is this will affect a lot of redstone contraptions. (This happens in 14w26b)

Please don't mark a future version as affected, because those are not released yet and can therefore still be changed. Mark the version you found the bug in instead.
