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.
Just upload the screenshot in the bug report channel and put the bug report as the caption for the screenshot.
