So, I've been paying attention to the pumpkins for some days now and they are not working properly. First of all, it seems like the timer is reset each morning so no matter how long it was left for the next pumpkin, the timer is reset to zero. So for the small field, you should have only a couple of minutes left and then it's reset to start over again and then it's 8 hours left. So this means that for the last week, the small pumpkin semataries have been giving only 2 pumpkins per day instead of 3 that it should. I did the maths with the number of pumpkins left and it adds up.
Furthermore, the time is not the same for all semataries. This morning I had exactly 8 hours left on my small semataries and 4 hours left on the common. Now, 5 hours later, there's a difference of 20 minutes.
So how on earth are we supposed to keep the pumpkins buffed when we have no idea when the pumpkins are finished? I have no idea hoe many buffs and pumpkins I have lost to this bug.
