The first should be ‘are’ not ‘is’. I understand it depends on the name the player gave to their group, but ‘and’ would be more grammatically correct more often than ‘is’, as it’s always a group of people being spoke of.
The second I don’t know if it’s a bug or not, but that character looks like a missing character glyph. So maybe it’s supposed to be something else the font in the game doesn’t otherwise support? Just drawing attention to it, I suppose.
