Please provide any additional information below.
The crash appears to be sever strain after the severe error and causes by the fact I have other plugins that it is interfering with.  I have disabled all plugins besides pail (so I can see console) and sponge restore and the error still occurs (without crash though, so reason for previous statement.  Does cause sponges to vanish visually, pistons malfunction, ect ect though).  I also have disabled the plugin and the error does not occur when playing with the doors.  I BELIEVE it involves the fact i'm moving sponges with pistons (to create hidden doors and such in a sponge building).  On a side note I see redstone activation is up on the todo list, you should add configuration option to disallow that for people such as myself who like to build with the spongy material as a primary block and not JUST remove lava/water/fire.  I figure you had considered this but thought I would throw it in there since I am taking the time to write you about the issue im having anyway :P

Almost forgot bukkit build.  I am running the one they released for the 1.2 upgrade to minecraft I am not sure of the official build number offhand sorry :/ but I figure you should know the one since it was a big deal cause of all the updates features :p

This definitely sounds critical. Sadly, I don't have the time to address it until DisguiseCraft is stabilized.

I always had a feeling that the piston support would have huge issues like this...
I may also have to implement an option to disable the pushing/pulling of sponges completely.

If I do not get back to you about this within a week, be sure to notify me.
