Not sure if related to the changes to the caching but now searching for 本好き (and only 本好き…) gives me an error. Thought it might be related to the JP text but nope, other JP text searches work as do English (including “bookworm”) as does just putting “好き”. Replicates for me on both Chrome and Firefox Android.
(I was looking for Parts 4 and 5 of the manga, I think they still don’t have English titles so they don’t show up when searching for “Bookworm”.)
