Item ID problem

[JamesCMaxwell]

Mods installed: Voxel map, not enough items, bibliocraft, witchery

 

What happened:

 

I started a map with just witchery installed and then added voxel map, not enough items and bibliocraft later (I think this is important for reasons explained below)

 

I accidentally loaded the map using vanilla 1.7.9 MC. Realising my mistake, I opened it again with my 1.7.2 Forge profile but the items were not as I left them. Specifically, all the mod items in my chests and inventory were lost and the placed items had changed. It appeared that witchery items had become bibliocraft items and vice versa.

 

I felt this had something to do with how Forge had loaded the mods. Perhaps, because of the order in which I added the mods, it had initially loaded witchery and then bibliocraft but it was now loading them the other way round, thus switching the IDs (this is pure speculation, I've no idea how forge works).

 

I figured it might be loading bibliocraft first as it is alphabetically before witchery, so I added a 'Z' in front of its name in the mods folder. In order to see any change, I had to open the world in vanilla 1.7.9 again and then in the forge profile. When I opened it again using forge, the witchery items were back to normal (although I'm still missing the items in my inventory and chests) but the bibliocraft items were not. The bibliocraft stuff is now bibliocraft stuff again, but not the right bibliocraft stuff (so the bookcases became poppet shelves which are now fancy signs).

 

Any ideas what's going on here and what I can do to fix it? Thanks in advance.

 

Edit: The world has now started crashing when I load it. Here's the crash report:

It mentions the poppet shelf and the fancy signs at the beginning. The poppet shelf replaced the bookcases initially. After I added the 'Z' in the bibliocraft file name, the fancy signs replaced the poppet shelves. When I enter the world I spawn next to these signs.
