No styles for reactions after update to 4.2

[Refsmmat]

I have just updated my forum to 4.2 and found quite large reaction icons:

 

Digging a little bit deeper into it, I found, that the update didn't leave any "ipsReact*" CSS styles anywhere. 

So of course the reactions are not displayed properly.

Question is: is there a chance to get the needed CSS styles posted here so that I am able to paste them manually?

Many tanks in advance!

 

Regards, Tom.

Never mind. Found the styles (engagement.css) in the 4.2 Admin Panel CSS

I'm having a similar issue, but in my case none of the default icons are showing after upgrading. Any ideas? Where did you find these large default icons?

Is there a way to make the "heart" go back to just the same like button it was in 4.x 

I don't want Facebook ripoff 'reactions'.
