 Description   

if you make a redstone contraption like this whit a music disk C418 - wait in it. the repeaters blink on and off but the comparators don't unless you give them an update when the redstone turns on. also when you right click the comparator in front of the jukebox 2 times when the disc is inside the 3 comparators will stay on.

Note that this can be reproduced with any power source in place of the jukebox. Destroying and replacing the comparators (near the repeaters in the pictured setup) will sometimes cause them to remain active, depending on the timing of the placement.

Can confirm in 1.17.1.

Comment by [Mod] j_p_smith [ 19/May/20 ]

Confirmed in 1.15.2 and 20w20b.

Comment by Kraif [ 05/Sep/18 ]

Confirmed for 1.13.1. Please, keep the ticket updated.

Comment by [Mod] NeunEinser [ 24/Jul/17 ]

I think this is at least related to MC-8911. This bug describes a behavior, where the comparator does not blink/ react unless you spam right click on it.
Anyways, can confirm for 1.12

Is this still an issue in the most recent versions (currently that is 1.10.2, or 16w42a) of Minecraft? If so, please update the affected versions and help us keeping this ticket updated from time to time. If you are the owner/reporter of this ticket, you can modify the affected version(s) yourself.

Can still reproduce in 1.9.1-pre3. Comparators stay off for me this time.

Comment by user-f2760 (Inactive) [ 18/Mar/16 ]

No response for over a year.

Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases. If this has been done, we can reopen the issue.

Keep in mind that the "Resolved"-Status on this ticket just means "Answered", and that we are waiting for further information on whether this issue still exists or not. We will reopen it as soon as the requested information has been deliviered.

Confirmed in 13w11a, although the comparators seem to stay on instead of staying off.
