Alternate textures disappear when I load my mod in GECK

[TorrentialDefect]

I've been having some problems with texture sets lately.

I made a 10mm pistol for my mod which is statistically exactly the same, but it has the alloy steel textures from Operation Anchorage.

After I applied the alloy steel texture sets on the gun's model itself, I did the same for the models with weapon mods (extended mag, laser sight, etc)

This is what the model for 10mm pistol with extended mags looked like. I saved the mod, closed GECK, went to sleep.

 

In morning, I opened GECK, I went to check the Anch 10mm Pistol textures:

The texture sets on the 10mm pistol with ext. mags had vanished completely. Same happened for the other models with weapon mods. When I checked the default model (the one without weapon mods) the ext mag model's texture sets were somehow applied to the default model now.

I've been trying different models, different texture sets, different mods, I've reinstalled NVSE and GECK Power Up and IT'S STILL THERE. Even loading the mod without Powerup or NVSE didn't help at all.

This bug is driving me insane, I really need some help with this.

 

TL;DR: When I apply texture sets on a weapon mod model, it disappears after I load the mod in GECK again.

 

EDIT: Reinstalling the game didn't help.

After loading the mod in Geck Powerup 1.4, I tried to change the 10mm pistol's unmodded model, only to get the above warning message.

Bump. Any ideas?
