I am sorry it has taken so long... they all turned out to be simpler 
than expected.

1. The corrupted instVars bug - sorted : thanks to Matthews 
investigative work it turned out to be a really simple fix.

2. The FFI doesnt load bug - sorted : thanks to Andreas for his 
inspiration as to how to fix that.


The best way to load FFI is (because it includes the prequisite fix for 
NetNameResolver)...

Start with LevelPlayingField see 
http://installer.pbwiki.com/LevelPlayingField

Installer install: 'Packages'.
Installer sake addPackage: 'FFI'; install.

enjoy because MC1.5 has finally made it to what I had intended all 
along, and it passes Lukas' nasty test case.
