Can't find existing kbin magazines, tried on two servers

looking for @rimworldporn@rimworld.gallery (already exists on lemmy.world) and @rimworldart@rimworld.gallery gives me no results.

I do see the request come in on the server

[31/Jul/2023:18:26:41 +0000] “GET /m/RimWorldArt HTTP/1.1” 200 1942 “-” “Lemmy/0.18.3; +https://lemmy.world”

Searching from other kbin instances works fine
