On my 3rd guardian and can't get the emote gift from Tess. It says "Can only hold one at a time." even though I don't have it. And I have more than one emote slot free. On PC.
Nevermind, I figured it out. For anyone else having this issue, I came across this random solution in a Reddit thread. If you equip your Point emote and then try Tess again, you can grab the emote gift. I also stashed all my other emotes just in case and pointed once before I talked to Tess. Weird bug.
