I just found out some of the buttons I use to link to my website no longer work, but that for some reason the one linking to my Steam group still worked. I’m guessing there was an update or something to the Steam overlay preventing non-Steam links from being opened.
Anyway it wasn’t hard to find a quick fix for this. Simply replace your link like so:
[lua]gui.OpenURL(“https://facepunch.com”)[/lua]
becomes
[lua]gui.OpenURL(“https://steamcommunity.com/linkfilter/?url=https://facepunch.com”)[/lua]
Links were working normally days ago and all of a sudden they stopped working so I’m thinking the issue (restriction?) is related to Steam itself.
