Team globals on S,4 mobs?

Noticed this team name on HOF board - a team globaling in solo instance and team instance in the same run (or any team globaling in a solo instance for that matter or even being in a team while in a solo instance)?

I'm not sure if a person can be in a team and still enter solo instance and have that name show in globals or not - verified tracker against my EU chat log and it did indeed show a team global in a solo instance for this team.

Dunno if this is an oversight from devs or someone playing around, any one know?

Probably in a team but playing solo to hide who they really are and how many globals they're getting.

Was my guess too, didn't even know you could enter the solo instance while in a team...

Known bug..
