Messages - Pics/Vids dont show

I have a group chat with 4 mates going all the time. If anyone shares a picture or a video it doesn't show on messages. I get the text if they have typed anything but no multimedia.

It still shows correctly from iMessage from my iPad and iPhone.

I can send multimedia from Messages and others get them but they dont show on my iMessage feed in my iDevices.

This seem to get fixed during one of the last OSX updates but all of a sudden it has stopeed working again.

No pics or vids show in the Messages App on my MBP in ML.

Anyone else having the same issue?
