Can somebody explain how UE4 is violating the laws of what should and shouldn’t be possible with software…
I post here in tandem because frankly, nobody checks answerbase unless you rub the problem in someones face here on the forum. I cannot figure out why my asset is changing every-time I open my project, even though it’s not saved this way. Somehow between closing and opening the project, my connections between nodes are breaking. How?!
Great, now after trying to fix it my project is COMPLETELY un-openable. That reference tool is completely busted -.-
Lost a days work now because of this issue.

Edit: Scratch that, lost MANY days of work. Not happy.
I am assuming you went back to autosaves before the problem started?
Unfortunately, if you deleted some assets that the blueprint was referencing without somehow removing ALL references to it you may have broken the compiler or something. I did this a few days ago and it was a disaster.
First, never force delete. Track down all the references and make sure it doesn’t throw up any flags.
Second, never delete directly in the project folder because that is basically force deleting without any flags to warn you otherwise.
So anyway, what I had to do when I broke everything, was to manually copy and paste everything from my broken blueprint into a new blueprint. If you make a new blueprint it will only have the references you add, copy/pasting everything should work fine.
You might be able to migrate it using the editor migrate options, but when I did it I wanted to be **** sure I didn’t migrate any of the gremlins to the new blueprint so I did everything manually.
Your error message isn’t the same as mine as mine specifically referenced a blueprint and some asset I force deleted, but if you can at least narrow it down to an offending blueprint, then abandoning ship may get you past this.
I’ve managed to slyly piece it back together, by merging together (manually via Windows) various assets into about three different projects. The offending blueprint was the same one linked above. Luckily I had an old backup on Google Drive to piece the rest of the code back together.
I did try to re-reference everything via the reference editor. The reference issue came from various castings I was performing between assets, they didn’t get redirected to the new assets. That was part of the issue anyway.
