K, gonna jump into this one. Certain items can't be transferred simply because they've been set not to. Why? Well that's because they have the potential to 'break' things + noobs buy them off people then bitch at us about them not working. They became collectors items after they somehow ended up in users inventories.

Examples are: Body texture item - an old test from the days of not being able to transfer textures
Long/Short/Slow motion ghost items - they just don't work full stop
Alpha/Beta - no idea what they were even made for
A test item - yes, there's an item called that lol

Well I could go on but I wont, basically they're things that were never supposed to end up in user's inventories. "Body Texture" is the most common because it was put in texture packs for some daft reason.
<- his fault that happened.

Other collectors items should transfer unless they were specifically made not to, like the Magic Cucumbers (designed to annoy whoever I dumped them on).

The real collectors items that were specifically made for collecting will transfer normally.

I hope that clears things up, I tried to avoid making a wall of text.


They do work, but there's so many to do it's running out of time on it's daily run. Patience is the key.
