Hello, i'm here again for more problems
lately the moderation action of spoilering images isn't working anymore

before it worked like this:
-post images inside a thread appear as spoilered right after spoilering them by moderation
-OP images didn't spoiler right away after getting spoilered by moderation, but the change appeared only after the catalog got refreshed by a new thread or an other thread bump

how it works now:
-OP images remain unspoilered after getting marked as spoiler by moderation actions, and even after a catalog refresh the OP image remains unspoilered

examples (nsfw bot spam)
 >>/dump/1122/
the image in that thread op was already spoilered by moderation actions, but it's yet not spoilered even after the catalog did change
 >>/dump/1104/
this same bot spammer thread had the image just deleted because this no-spoiler issue started to be noticeable yesterday
 >>/dump/432/ this was the first occurrence of this same bot spammer

I know I can just delete the rule-breaking images(that still works at least), and wide range ban the bot, but I'm interested to know why this specific spoilering action isn't working anymore, I'd rather still have that tool available if possible

Are OP images no longer be spoilerable only for /dump/ or is this happening on other boards too?
Has something changed in the site-wide page structure lately, and could that change be causing this?
Or what could otherwise be the cause of OP images no longer spoilering by moderation?
