 Description   

Update - I also created a bug demonstration video available here: http://www.youtube.com/watch?v=eQlSnJtLUNc

Steps to reproduce:

  1. Build a long redstone wire with repeaters far away from the spawn. ("long" = more than about 12 chunks; "far away" = teleport 1000 blocks away and you should be fine)
  2. Go to the beginning of the wire and power it (by placing a redstone torch in front of it).
  3. Follow the wire.

You'll notice something like in the screenshot "light-emission-bug.png": The light emission was correctly updated for all repeaters that have been located in loaded chunks when the wire got powered. (Like the right repeater in the screenshot.) It was not correctly updated for all repeaters further away. (Like the left repeater in the screenshot.)

This ticket relates to MC-1018. (Reason: If the lighting engine has to be rewritten anyway, this bug could be taken into consideration when designing the new version.)

Because that ticket provides better information.

Okay? Just curious: Why do newer ticket "win" over older tickets as being the duplicated (not: duplicat*ing*) ticket?
I mean, this ticket is from 2013 whereas MC-93132 is from 2015. Shouldn't the status on this issue rather be tracked here in this ticket?

Ticket was already resolved to MC-93132.

Comment by The.Modificator [ 29/Oct/16 ]

Updated. Please reset ticket status.

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.

I can confirm this issue also occurs with redstone lamps that are triggered remotely (either by a long redstone wire, or using the Craftbook-provided transmitters and receivers). The opposite is true as well: a lamp that is switched off remotely keeps emitting light even while its texture indicates that it shouldn't be doing that.

After hitting the lamps a few times with a bare hand, the block seemed to update and started to emit or no longer emit light. However, this does not always work.

Server version: 1.8.1
Client version: 1.8.0 with some mods (Forge Modloader, Liteloader, Optifine). It also happens with an unmodded 1.8.1 client.

Reopened, thanks

Problem continues to exist.

Comment by Galaxy_2Alex [ 25/Oct/14 ]

Is this still a concern in the current Minecraft version 1.8.1 Prerelease 3 / Launcher version 1.5.3 or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

Is this still a concern in the current Minecraft version 14w11b / Launcher version 1.3.11 or later? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.

Whoops - sorry. This bug still exists in 1.7.2.

Comment by Talven81 [ 26/Nov/13 ]

No response in 4 months, assuming no longer an issue.
