Mine from two days ago was censored by nervous "Sir Authorities". HA!
Well, whatever, though.
Main subject. As one might expect, some people are aware of this, but just in case, I publicize.
Re-merging isn't possible unless the merged potion disappears after 24 hours.
In other words, merge is once every 24 hours.
This isn't possible until at least 24 hours have passed.
By the way, there is no point to manually Delete a merged potion.
I repeat, It's not possible to merge again until at least 24 hours have elapsed.
(I don't know if "after resetting housemaid fatigue" would definitely and reliably enable a retry. I would never use that feature in the first place.
Why should I give a 1M to those incompetent housekeepers? Ha!)
In other words, it is the same pattern as the "24-hour bug" immediately after the WoF "a change for the worse.".
Can't be retried until "at least" 24 hours have elapsed.
As I, and someone else, mentioned before, it could really just be unstable functionality. But, alas, it does not seem to be the case. Objectively speaking.
They guys're making the same mistakes. No progress.
This might be bad. This is really not good in a way.
