Hello I created ship "hiddev-dannut" to host the new Hooniverse group. A member filsur-sanmut could not see it, even though at some point he had to have had access because he was listed as a colored sigil with access. I clicked on the sigil and saw the expanded sigil page with his full ship name and the "Remove from group" link in the upper right. upon clicking that link, the entire group disappeared. It was confirmed to have disappeared from my other ship which was a member.

I recreated the Hooniverse group on that ship and invited a couple of former members. Those members immediately had access to all chat and group links (without re-creating them) and could post and be seen in those chat channels.

So in summary, a group got deleted from removing a member, and then once the group was re-created the chats and links were all there automatically. Only the members were gone. I am hoping that re-inviting the members does not lead to more of this disappearing group error.

Here is the error that filsur-sanmut got:

In case that is helpful.
