Back after delay,...
Just compared my css to another vb site I have, to compare the activitystream.css entries.
Guess what, on my problem website, the activitystream.css template is completely missing!!
All I did was uninstall the mod, and it looks like the uninstall process for some reason has effectively deleted the entire file, and on all subsequent child theme templates too.
OK, now I just have to figure out how to reinstall that particular activitystream.css template into my oem template.
THANK YOU Replicant! I was sure I checked everything. But I guess it is hard to check what no longer exists lol.

Soooo,...
Was unable to figure out how to bring back the oem activitystream.css.
As a quick solution, I added the template via admincp, inserted the correct code extracted from another site, and viola, fixed.
My only residual problem is now the activitystream.css template shows up as red and custom in my default oem template list. It is revertable to nothing now, or to explain, if it ever is reverted, the whole activitystream.css file disappears.
I can run it like that, but is anyone aware of how to make that an unrevertable template in my oem style just like it was after initial install?
Thank you everyone for your help.
