Bukkit

What steps will reproduce the problem?
1.Place The Quarry
2.Feed it with Fuel
3.It starts buiding the Quarry Frames

What is the expected output? What do you see instead?
Frames would be constructed, but at certain places, they seem to be missing. There's basically a force field that prevents me from getting inside the Quarry. I disconnect/reconnect, and the frames are now visible again.

What version of the product are you using?
The last one : v1.7.1

Do you have an error log of what happened?
Nothing goes wrong in the logs, it's just a client bug.

Please provide any additional information below.
None I can add :D

Hmm, this is odd, since I queue all block updates with bukkit using chunkupdates. I've never really had this problem. The only thing you can try is to make sure you're running CB 1.6.2-R0.1, with Java 7. Loads of server lag may also cause this, but there's not really much I can do about it i'm afraid. Let me know if you got it to work!
