'importing small assets' message when saving scene. Unusual. Weird. Strange Behaviour. Annoying.
This issue has been reported before but the discussion halted because it is deemed out-of-date or not reproducible. http://answers.unity3d.com/questions/370948/importing-small-assets-every-time-i-save-a-scene.html
It is not out-of-date and is very much reproducible.
It's an annoying little message that occurs 80% of the time(s) when you save a scene, but not always. It also seems to occur sporadically (1%) during editing. The vagueness of the message "importing small assets" makes the Unity3d user experience feel like it's sick, infected with a virus or spy or hack, or playing a secret joke of some long lost programmer. If it's not a bug or a virus or a third party spy, then I vote to have it either edited to explain which asset is being imported, or, removed entirely. It seems to suggest that Unity is downloading assets without explanation, without authorization, etc. (which is atypical of Unity everywhere else) and this makes the user feel less confident in the product.
I used to believe it had to do with importing from the Asset Store. I do not believe this anymore because my current project has not downloaded any assets. I also do not have any plugins. Perhaps it's the lights, which seem to behave differently than other 3d objects, so perhaps they are the cause and need to download something.
Please up-vote this issue!
I'm also having this issue, it's been happening for quite some time and was a sudden change. One day Unity began "Importing Small Assets" every time we saved a scene (or the project for that matter) and we haven't been able to track it down. At the time I simply assumed it was due to the size of our project since most operations have progressively slowed as the project grew.
If I get some time I may have to try stripping plugins from our project one by one to see if it has any effect.
I would love some more information because it costs us serious amounts of development time waiting for save to occur.
I also have this issue, very annoying! Which assets from the store are in your project? Are you also using the Strea$$anonymous$$gAssets Folder?
Were you able to discover the cause of this problem? Still having this issue as of 5.6...
It would be nice if there was some way to at least see in a log somewhere what Unity thinks it needs to re-import as a small asset. Does anyone know where this information may exist?

Dear god, this problem has been the bane of my existence since late 2016, and I've yet to discover how or why it occurs. And many others seem to be experiencing the problem as well: https://forum.unity3d.com/threads/importing-small-assets-when-saving-project.440027/
Unity devs, please, please fix this. I'm pretty sure this issue is way more widespread than you think it is, because like others, I assumed it had to do with the size of my project. But having rebuilt the project, this is obviously not the case.
I got rid of this problem, by deleting some files that caused the issue, but I'm not sure why these files caused trouble... I use the $$anonymous$$ega Splat assets and copied the asset files (for the texture setup) in another folder to customize them, after that I got the import problem... I just found out that they caused it, because there was a read-write file error window popping up (sometimes), which gave me the the file name that caused also the importing problems. So maybe checking ".asset" files or resource files might help...
I did a quick check to see if there were any import issues with any assets, but no such luck... Thanks for the update, though, it gives me hope.

@Talasas I managed to take a short video showing it happening but can't upload video so here's a screenshot showing it immediately upon saving the scene...

I had had same the issue. In my case, GoogleMobileAds.framework which is placed on "Assets/Plugins/IOS/" caused this problem.
I think that symbolic links in this framework caused this problem, because after I removed symbolic links the problem have never happened.
But this is not drastic solution. I need to put on the framework on the directory. I hope Unity Team will solve this problem.

In my case, the problem was caused by the Cache Server, it was stopped and the "import small assets" message appeared every time I saved a scene.
