Model fits ruined on scene reload

So I am making some models based off the greyliens base model, basically greylien with flames for hands and modded head. -- I haven't been able to get clothing/armor to fit on it correctly unless I start with the base model without modifying the arms. But if I just apply whatever to it before modifying (or modifying pose), then after clothing is on, I then cut off hands with the geometry editor, things work fine. (at least for the session I'm in)
(When I apply the clothing I click genesis 3 male, accept, for all items,which seems to work as long as pose is default and no geometry modifications)
Problem is, I just reloaded one of my scenes where I had cut off the hands and now the clothing isn't fit correctly at all. (not just arms, it's like the suit is there before trying to fit to character).
How do I stop this from happening and or is there any way to salvage the work I've lost?

Now even my model which I saved as a subset, which I know was working yesterday because I merged the subset into a scene and did a render yesterday, is all jacked. Which makes no sense. Possibly worth noting, Daz crashed my computer during a render just before all this started happening. (bear in mind that I did nearly 3 or 4 scenes with the one correct model and everything worked fine, now they are all corrupted. So seems unlikely that render crash could cause it, but idk?)
A system crash is probably down to soemthing overheating during the render, or a bug in the driver.
As for the fitting issue - I'm not sure what you mean, and more details would help, but one possible fix on loading the new scene is to fit the clothes to None and then back to the figure - this forgetting can happen with morphs that haven't been saved as a moprh asset so it may also happen with figure modifications which are embedded in the file rather than saved as assets.
Thanks, I will try the save as morph asset. Right now I'm too scared to save and reload my scenes after redoing the work I lost but I will post screenshots illustrating issue if it still doesn't work
