Fix SMP Bug -- Again

Sorry about this Pahimar, should've checked those values.
I've fast-forwarded and merged my branch so it wont conflict at your end.

* Fixed the obj1->obj2
* Reapplied the areWorldEquivalent call and ..
* Used the debugger to check that I couldn't transmute blocks in to something unequal.

I'll triple check my PR's for false positives in future :)

This branch is current to your HEAD commit 08152d8677
So it won't remove the localisation PR or your changes to WorldTransmution in `Some fixes`
