NoSuchMethodError - using AutoSaveWorld

Title: NoSuchMethodError - using AutoSaveWorld

Version: 3.1.2

OS: Windows 7 Ultimate 64-bit

Java Version: 1.7.0_13 64-bit

Description of Problem:

(Hopefully it is appropriate to post this here. My apologies if it is not.)

When trying to save the world using AutoSaveWorld (most recent version, released Feb 2nd) it fails, with the errors as below. I also tried it with Tekkit 3.1.3, getting the same error. This is with a fresh install of both Java and Tekkit.

For reference, it worked perfectly with CraftBukkit 1.4.7-R1.0 (the most recent version, released Jan 31st.) Otherwise, I certainly wouldn't post this here. It also occurs if the save triggers from the automatic timer. (The one that saves every 5 minutes by default.)

Any help would be appreciated! Thanks!
