 Description   

Build the attached setup, place a redstone block between the pistons and wait a few seconds. Alternatively kill yourself (/kill), fly away and come back etc. (same steps as to reproduce MC-177)

Actual outcome: Redstone block turns invisible.

Expected outcome: Redstone block stays visible.

Bug also exists for other blocks if you power them

Probably the same underlying issue as MC-177, but this particular issue can not be reproduced anymore because of changed piston behavior.

Thanks for the update.

Comment by Jonathan Haas [ 17/Mar/13 ]

Confirmed fixed for both the 2 and 4 piston setup in MC 1.5. The pistons are now behaving properly and are moving slower

Comment by Tails [ 17/Mar/13 ]

Unable to reproduce with 4 piston setup.

Comment by Jonathan Haas [ 01/Mar/13 ]

I filed MC-10677 for the new weird sticky piston behavior.

Comment by Anon Ymus [ 23/Feb/13 ]

Got it now. For me, there is both the redstone block and an invisible one that occupy the same space and experience z-fighting with each other. Upon destroying the redstone block, the invisible one continues around.

Comment by Jonathan Haas [ 23/Feb/13 ]

Bug seems to be sort of resolved with sticky pistons but still happens on normal ones.

If you build the 4-piston setup with sticky pistons it looks like the block is pushed through all 4 positions in one single tick, which is very weird. But at least it doesn't turn permanently invisible.

Behavior for non-sticky piston seems to be unchanged.

Comment by GrygrFlzr [ 23/Feb/13 ]

Confirmed to still occur on 13w07a with the four piston setup if no repeater delays are added. Reopened.

EDIT:
Actually, also occurs with 2-piston setup without repeaters after waiting a few seconds.

Comment by Jonathan Haas [ 23/Feb/13 ]

Still reproducible using the 4-piston clock with non-sticky pistons

Comment by Anon Ymus [ 22/Feb/13 ]

I can no longer reproduce in 13w07a.

Comment by Anon Ymus [ 10/Feb/13 ]

Confirmed.

Comment by Jonathan Haas [ 02/Feb/13 ]

This seems to be much worse with 13w05b as the block now seems to disappear split seconds after starting the clock.

Comment by Jonathan Haas [ 27/Jan/13 ]

Redstone not appearing to pulse is MC-5778

Comment by Joshua Staub [ 26/Jan/13 ]

Here's a video of the behavior I made. Also note that the redstone does not appear to pulse.

Comment by Jonathan Haas [ 04/Jan/13 ]

Also notice that this bug doesn't need a redstone block, on the attached screenshot the diamond block becomes invisible, too, after a few seconds.

Comment by Maarten Thijs [ 04/Jan/13 ]

confirmed, seen it in cubehamsters video http://youtu.be/gAAoKMU6dBw

Comment by Guybrush Threepwood [ 03/Jan/13 ]

you don't have to use /kill or fly away. you just have to wait or try again
