Oh I remember this game. That’s a feedback bug where the information was repeated three times, but ending up with two assassins at the same time (with 2 not being able to take any night actions) is a bug that should be reported in the discord channel for bug reports. Not sure if you did that already; you can upload the screenshot or logs from that game (if you haven’t already) and report it in the format:
.bug Title. Description goes here.
Note that the title ends in a period to separate it from the longer description.
What if I’ve played lots of games since?
Well, you probably can’t send logs, but you can still submit this screenshot
Just upload the screenshot in the bug report channel and put the bug report as the caption for the screenshot.
