It seems that the other room was frozen:

@Wrzlprmft Should that room be unfrozen?

Or should I ask StrongBad - since he is the room owner?

Since you happened to be here and you're a moderator, I have asked whether there is somethings that should be done.

@MartinSleziak Yes, did that. Could be that the bot that kept it alive has been deactivated. I will look into that later.

Thanks for the response!

Here is another room that was missed by the same bot: chat.stackexchange.com/transcript/92831/2024/5/9

OTOH the bot posted some message a few days ago: chat.stackexchange.com/users/382851/generic-bot?tab=recent
