I found bookshelves today, specifically in Wormroot Depths delve in Grahtwood NW corner, that would not open on the first few tries. The interesting part was that they said "shelves" for the interact prompt, in gamepad mode fyi, instead of "bookshelf" when they would work. My character would perform the opening animation and nothing would open, no book.
A friend also found chests in the Imperial City Sewers unable to be opened. They would say for the interact prompt "open" but they were still locked at their lock level. The one chest he found said "master" lock and prompt said "open" but nothing would happen when clicked.

This seems related to two other bugs. One is the bug with "Giant Warning" covering a lot of other books but not actually giving you the lorebook completion for "Giant Warning" in Eidetic Memory. The other is the long term bug with containers displaying as full then you try to open them with the opening animation but the container goes directly to empty with no loot window. I wonder if anyone has noticed if the interact prompt for those containers reads different than normal?

This definitely seems related to the "performance improvements" that came with Clockwork City because these bugs were never happening before or at least far far less common.
