This is known issue (but on the other hand I have never claimed that our mod is compatible with MCPC+). The incompatibility might get fixed if/when we switch from ASM to Javassist (not before porting to MC1.6.* is done).

Should be fixed in mnn/monnefcore@e9d2760 (it will be included in version 0.5.1).
