Normally you’d never teamchat in play solo (there’s no one else there to be on your team), but I did because I was making a custom chat GUI and couldn’t remember what it looked like (a teamchatted message). I tried teamchatting so I could recall what it looked like, but Studio crashed both times I tried teamchatting in play solo (tried more than once to make sure it wasn’t just coincidence).
This is still a problem, not big a deal; but an issue.
