Hey all, despite seeing several Youtubers (recently) successfully initializing and running calls from PeterUCallouts, I just get a red error at the bottom of the screen saying it failed to work for every single one in the list. Any suggestions?

PeterUCallouts is out of date and unsupported. Keeping plugins in your game that are out of date will cause crashes and game instability! Remove them 🙂

You think these streamers are running an older version of LSPDFR to keep the callouts working?

They may be old but that is a possibility. But there are new callout packs being released every week 🙂
