Rail duplication Glitch

confirmed for 1.8.1 pre-3

I've attached a simpler reproduction, better suited for a bug report than in-game exploits. When you push the button, the powered rail will drop into 2 powered rail items. It doesn't matter which side of the hole the normal rail is on or which type of rail it is, as long as it's not facing into the hole.

What seems to be happening is that the powered rail getting pushed which has two effects: (1) the adjacent rails are checked for needing-to-rotate, and (2) the pushed rail updates itself, presumably to update its power level. But when the adjacent rail rotates during step 1 it updates all of its adjacent blocks, including the pushed rail which causes it to drop. And then step 2 doesn't notice that the pushed rail has already been broken and so drops it again.

I was able to reproduce this in 1.8.3 with golden, detector and activator rails.

This has been in here forever.. when will it get fixed? 1.8.3 still doing it... my players are making rails as common as wheat....

Bug appears in version 1.1 so it is "only" 3 years old bug 😉

You automatically watch (but does not vote to) any issue where you comment or make a change. That's why there's a lot of people watching, but not too many voting.

Fixed, with thanks to @unknown!

I kinda fell dumb now, fixed in 5 hours after send tweet to Dinnerbone. Why I didn't do that like year ago.

That was my point, Bentroen... seven people bother to comment, but only three to vote... Who would not think this needed a vote?? I'm glad it is actually getting fixed now.

It's likely that not too many people voted because they actually used this bug. I mean, I can't say I haven't used it myself, but I'm still glad it's fixed now. The less exploits the better in my opinion.
