PKHex not saving form changes, even in hax mode (B2W2)

[Merlinn.-]

Currently playing a W2 Randomiser, and trying to change the form for my shaymin. However, Despite PKHex showing the sky form, when i load the save file into DeSmuME the form change doesent appear. i have tried this both in normal and hax mode, and the change doesent apply in either. Other changes, such as changing the nature and IVs do seem to be working, however.

Save file as opened in normal PKHex:



Save file as opened in PKHex in Hax mode: 

What appears in-game:
 

The nature has changed, which i edited to timid.

Even when i re-export the file from DeSmuME, The form remains as sky in PKHex.

The game automatically reverts the party's forms on startup and after battle.

This is not something a save editor can bypass, unless you leave them in the box.

Well, it seems to be working if i edit it into the box, then take it out. Doesent reset when i exit the battle or box from what i can tell.

It does change back when i put it back in the box, but that seems to be the only time when it does.
