What is the problem?

Rebuilding a player's edits or undoing a stupid rollback sometimes fails if the user made signs, furnaces or dispensers, with the following error..

05:42:51 [WARNING] Task of 'HawkEye' generated an exception
java.lang.ClassCastException: org.bukkit.craftbukkit.block.CraftBlockState cannot be cast to org.bukkit.block.Sign

Additionally, when rolling back, we sometimes get this error..

java.lang.NullPointerException

What steps will reproduce the problem? 1. Undo someone's edits [Sometimes causes the second error] 2. Undo the rollback or rebuild the user's edits [Sometimes causes the first error]

What version of HawkEye are you using (shown in console during start-up)? 1.0.7b

Show me any console errors and/or your start-up console message for HawkEye

Yup, I got this error too. Messed my whole world up. Thanks a lot hawkeye... I thought this was supposed to be different than LogBlock? Its as, if not more, buggy than logblock.

@x_clucky: Go

I think it hasn't been updated in wtflongtime. I'm hoping someone makes it possible to port the database to Guardian or something...
