Yepp. Feel free to shoot us (moderators) a message if you figure out what it is. I assume Steam is downloading Cloud Saves or sth, but this is not confirmed.

well looking at my steam folder the relevant files seems to be appmanifests and gameoverlayUI files.
theres nothing modified in the Valheim library since the 17th.
so that tells me it has to be Steam just tweaking config files or some such.
doesnt explain why its linking to Valheim though; unless its the way they sync your Steam UI with relevant data for the games you play?
