Asset bundle reflection map

Hi guys!
I`m having a problem with asset bundles and lightning.
There is an object in my assets folder and the same object,but it is loading from the server, using asset bundles.

The left object is from project folder, and the left one is downloaded from asset bundle (screenshot was done from Game tab, after bundle was loaded)
the problem is - after i download my object it wont render as i expect:
there is no reflection and its too much light on it.

Here is the screenshot of the materials. on the left, there are two materials from asset bundle loaded object, on the right - materials of the object from the asset folder.
All lights in the scene are realtime.
Unity version 2018.3.0b4.
Reflection comes from custom Environment reflection (cubemap).
Thanks in advance!

 

I`ve tried to download Materials using asset bundle, and i saw same situation.
material which was downloaded - wont reflect(

 

after a bit of testing, found a workaround - if you change your shader on already downloaded material to something, and then back to Standard, everything works.

 

any updates on this?

 

I realize this is an old post, I'm having this exact problem right now. Did you ever found a workaround?
