If a player's username contains underscores at its beginning and its end, it will be relayed to Discord as if those are formatting characters, hiding the underscores and making the rest of the name appear either italic or underlined.

This could be worked around by always wrapping usernames in backticks but that's not a very nice way to do things.

I suggest that there be an option to insert backslashes in front of underscores in player usernames when relayed to Discord to prevent this small annoyance.

Fixed in 3.2.3
