It works with all items that can be charged.
Items from the builder is not removed and the chest appears.

i'm guessing this isn't fixed yet?

Suggestion:

Make a blacklist for blocks that should not be coppied :/
So we just need to put them there!

@EverNife its better to actually fix the bugs than add a blacklist. Especially as this affects vanilla items as well.

@EverNife There is whitelist for blocks, so no blacklist is needed.

I had not read that properly, forget it...

I will remove all vanilla chests... that may solve my problem, as a temporary action

Remove all vanilla chests from what? This most likely affects every inventory that contains a damaged tool as well, not just a vanilla chest.

I think this does not copy blocks from all mods, just vanilla ones...

At least in my server it copy only vanilla blocks...
So, for me, i till solve :D

@EverNife Are your sure you are having the same problem as this particular dupe bug?

Bc only supports vanilla blocks unless you have Bc compat. If you have bc compat, these blocks are supported by the builder and may also dupe items: http://www.mod-buildcraft.com/pages/faq.html (see compat question)

Pretty similar, but with draconic chests...

When you say ALL items that can be charged what items have you tested with? What mods are they from? Did you do this in creative mode or a server set to creative mode?

Also what version of BuildCraft is used?

dupe work on:
buildcraft-7.1.16
buildcraft-7.1.14
Dupe works in a creative mode and survival.
For dupe can use any that can be charged on the modification industrialcraft 2 experimental
Dupe can:

• quantum armor (ic2)
• nano armor (ic2)
• jetpack (ic2)
• graviTool (GraviSuite)
• vajra (GraviSuite)

and any other things which are charged.
Dupe essence is that things from the builder is not spending if there are items that are charged. Sorry for bad english.

Just tested with BC 7.2.6 and can reproduce in a survival world.

Steps to reproduce:
Record a blueprint with a chest with some pickaxes inside
Place a builder with the blueprint in and fill the builder with the contents inside and power it

The result: The chest is placed and filled with the required pickaxes. The pickaxes are also left inside the builder which results with twice the amount of pickaxes; a set in the chest and a set in the builder

is this fixed? if not it should probably be looked at soon as it's a dupe bug?

Bug not fixed. Builder not check meta item.
