i agree with dragavon and lordy. if u dont have salmon then put feasts on once per day same time everyday!
it sounds like u only have 1 of each market and tree. maybe put them aside till u can get 2 or even 3 of each and i'm sure u'll find buffs a lot easier to manage.
I have 2 xmas markets and 3 love trees.
The one fully upgraded xmas market runs every 12 hours - except when love tree is running, which is next to it. Love tree cooldown is 40 hours which is not great so I run it every 48 hours at the same time of day each time.
I'm just suggesting there is a gap in the buff market - we have a 6 hour 100% and a 24 hour 100% but no 12 hour 100 %. Lots of features (in my game anyway) have been organised to run on a 12 hourly cycle (or multiples of) so it would be helpful to keep things in sync.
Sounds about right to me. Reasonable suggestion. I needed such buff myself on several occasions.
No idea why anyone should oppose your suggestion. They don't have to produce it if they don't like it. And if they get any free they can gift them to you or anyone who will want to use them.
the way i play, i need a 12hr buff too.
i'll gladly produce it just to fill up my needs . atm needing 64 of them every day
