Problem with Forge Modloader > 829 and TreeCapitator 1.6.2.r01

[CaerMaster]

It's not clear to me where the problem lies, but there is a problem with the combination of TreeCapitator 1.6.2.r01 (the current version for Minecraft 1.6.2) and Forge ModLoader build 830 and higher.  Up to build 829, everything works perfectly.  With build 830 and above, TreeCapitator silently fails to load, and any attempt to break a tree block results in an internal server error and disconnect.  The server logs this:
