This is [Math.uasset][1]. It saved and compiled before restarting Editor.

Thanks! I’m getting same bug when I drop this in a new 4.7.2 project. Was this created in a version of 4.7, or in an earlier version of engine?

It was created with 4.7.

Thanks Villason! I didn’t see any obvious reasons for this to be happening (no circular dependency issues or unusual references that I could find). I’ve entered a bug report for developers (UE11411) with .uasset so they can take a look and see what might be happening here. I’ll let you know as soon as I see any update on it. Thanks!

Hi lovatt,

When you say copy/paste a static mesh in Viewport of an Actor BP, do you mean in Components tab? I’m not able to copy and paste within Viewport. When copy/pasting a static mesh component in components tab, I don’t get any saving errors on BP, but I did get one on map. If this is what you’re seeing, I would like you to create a new bug report post so we can track behavior there. Thanks!

I had problem too. A restart of Editor solved it.

Hi Villason,

I apologize that I missed it, but this was fixed internally and should have been included in 4.7.3. Please let us know if you’re still seeing this problem in 4.7.3 or later. Thanks!

Having same problem on a material (!) today, can’t save it anymore. Recreating it through copy/paste didn’t work. After I deleted all comment nodes (!!) out of pure desperation, I was able to save again. WTF.

I think Villason’s issue was particular to his project, and while fix applied to his situation it might not apply to yours. There was another main issue that was causing this that has also been fixed (can’t remember number off hand) as well. If this happens again, can you create a new post for us so we can take a look at yours? It being a Material makes me think it may be something else. Thanks!

I’ve just seen it in 4.7.6. I edited a code file where i added a UPROPERTY field because i needed that extra property in widget i was creating for it.

A restart of editor can’t solve your inability to save an asset, can it?
Because when you close it, it’s gone and you can’t ever attempt to save that exact state again… because it wasn’t saved when editor closed.

Hi Stino,

issue OP was running into was specific to Blueprint Function Libraries and circular references, fixed in 4.7.3. You may be facing same problem but from a different cause. Please open a new post in Bug Reports section with as many details as you can provide, including reproduction steps if you’re able to recreate problem in a new project. Thanks!

I got this when added:

UPROPERTY(BlueprintReadOnly, Category=“Collision”)

class UBodySetup* ModelBodySetup;

“Graph is linked to private object(s) in an external package. External Object(s): BodySetup_6”
