Since the recent update bots are in a weird limbo. They won’t receive any messages (room or direct) unless they are forced to move to another room. It might be related to them not appearing on the room counter either (making bot leave the room resets the pop to -1). It’s strange that it affects the private messages to, but idk.
Restarting the bot doesn’t help and the bug persists. For librarian, the bot got fixed when force moved to another room, for scam I had to put it to sleep and wake up a couple times until it started receiving the messages again.
