Loading.IDRemapping with 136244 calls!?

Using version 2017.4.25.f1 I experiance very strange behaviour when I try to use the inspector for certain perfabs. Any action with the inpector causes everything to freeze for 3 seconds!

Checking the profiler I can see Loading.IDRemapping making 136244 calls!

I have attached a screenshot of the profiler.

Anyone? Any ideas?

Update: seems to be less when a smaller scene is loaded.

Got the same issue since yesterday on 2019.2.14f1

@CoolJosh3k Any insight since september ?

I have no updates to this unfortunatly. When working on that project I don’t update to a newer version (this caused physics issues).

I found a thread on answers. It may be related to it: Loading.IDRemapping AssetBundles - Questions & Answers - Unity Discussions
I actually have the same problem and I think It really can be beacuse of big AssetBundle. I will try to split up it and see what will happen.

Thanks. I will look at that.
