My prefabs are suddenly broken

I came back to work today and found that I could not place some of my prefabs into my scene. I get this convoluted error:

When I select the prefab, the inspector is blank, Earlier there was a message displayed in the inspector, saying something about not being able to modify certain components, but now that message is gone and the inspector is just blank.

It wasn't like this when I was working on it last week. The only thing I changed was a slight revision to the script SOME of these prefabs are using, but then I changed it back to the way it was and I still have this BS error.

 

Well I've already deleted the corrupted assets and rebuilt them. I had work to do and had to move on.

But if it happens again I'll submit them with a bug report.

 

I just had the same problem, with a simple prefab composed of a few sprites, no scripts attached.

 

I've had this exact same issue repeatedly. I can only use the prefab for one play through when I push play then I have to replace the corrupted file. Oddly enough it's the same prefab file every single time.

 

I just lost 6+ hours of work due to this issue. I am quite vexed as I have a long list of things to finish and redoing hours of work was NOT on it. I saved the prefab and everything was working fine. Closed unity to restart computer while I took a meal break and when I returned, opened unity and pulled the prefab in to work on it...and I get the error. Can't even fix the prefab as it won't even drag in to the scene.

 

I found that it happens when your game crashes after doing a bunch of things (like creating new assets like prefabs) but not being able to save your scene because of the crash. Once you reload, you are opening an outdated scene that is confused about all the new stuff it's seeing inside its folders. I save more often now to avoid this, since unity seems to crash fairly often when it doesn't like something.

 

I started following the 2D rougelike tutorial to adjust to the unity 2D system for my next project. I had this issue with the prefabs I made that consisted of single image tiles (food, floor, walls, and exit). The prefabs that came with the project still work fine. Here is the error code for ElvisAlistar 746079

 

A guess: could it be that your scripts are manipulating the prefab itself instead of an instance of it?

 

Deleted missed scripts does not help. I have created new prefab, deleted object in scene then reinserted prefab into the scene and it finally become blue.. Hope this will help somone

 

So if anyone in the future has this problem try,

• Renaming the script in unity
• Reload solution
• Then switch the name to the same name but this time in C#
• Save, then reapply the script to the object

At least that works for me

 

Mine was due to a line in the script for PUN2. //photonView.TransferOwnership(PhotonNetwork.LocalPlayer);
