I don't know if it is a Buildcraft bug or a bug from another mode but we have a weired issue, sometimes Coal looks like cobblstone in the Pipe but it is coal and get handled correctly.

Screen (hard to see the cstone on that screen but look the coal):

I think something is corrupting your packets.

i noticed something similar but only on cauldron server with some protection plugins.

Can anyone reproduce this without Cauldron?

Optifine?

We don't use optifine, and weired thing is we haven't noticed that bug in the past, updated some modes including Buildcraft some days ago and then it appeared. Can't really reproduce it without the Mods as it is hard to remove them and so on..

Also have another visual Bug, I see combustion Engines Running while they don't run.
