[Opensim-users] Save OAR - Unrecognized asset type 57

2022-10-10 17:31:13,429 ERROR [ARCHIVER]: Unrecognized asset type 57
with uuid e13b140c-eefb-9e7d-b5e3-a3bec2022337.  This asset will be
saved but not reloaded

Hi folks.  I have started to get this error (with a reasonably recent
0.9.2.1 dev master) when saving an OAR from a previously good save. I
get about 5 of them referring to different UUIIDs.

I can't see what asset type 57 is in the usual data base asset values
wiki pages.

Anyone know what this might be and how to track it down?
