Had the same problem before. There's a workaround for this in that you can just drop a normal peach (in the Use tab) on the stone bench, which you can get from whacking the peaches in the Peach Farm area (I think you get some from one of the quests too). You can still get Tae Roon's note with a normal peach.
Of course, we shouldn't ignore the bug just because there's a workaround, so someone should forward this bug to the right people.
Unfortunately it looks like in this case the in-game list is the one that's incorrect Found this Reddit post that says the chair was obtainable from the "Choco-filled Veins" achievement in the previous version of the event, but now it's just a 100x Spell Trace Coupon in-game.
I guess they just scrubbed out all the interesting rewards from this event?
Edit: It looks like one of the achievements rewards a Clean Slate Scroll 10%, but there's no alternative listed for Reboot. :V I wonder if an alternative exists and they just forgot to list it, or if they forgot to put in a Reboot alternative entirely.
So I recently opened up some Damage Skin boxes from the Alliance shop and got my hands on one Foggy Damage Skin (Unit). I knew what unit damage skins were like in KMS, so I was interested in seeing how they ended up porting it over to GMS. And... well...
To give a really simplified explanation:
In English, to break down bigger numbers, we usually partition the digits in threes using commas: a billion would be 1,000,000,000. In Korea, to break down bigger numbers, they partition it into fours: a billion becomes 10억0000만0000. Still 9 zeroes, just separated in different ways. Here, the 억 refers to a value of 100,000,000 and 만 refers to a value of 10,000. In KMS, unit damage skins put the 억 and the 만 between digits, like so:
So instead of something like 311528805, they'd get 3억1152만8805 and they can easily parse how much damage they're doing.
And when they brought this over to GMS... well, you can see from the top image. But basically they translated the 억 and 만 values directly to 00,000,000 and 0,000, so Koreans' 3억1152만8805 becomes 3 00,000,000 1152 0,000 8805 for us.
So, uh, yeah, it would be nice if you guys could come up with a better way to handle unit damage skins instead of leaving this as is.
The reveal of the new Maple Missions presents new rewards for participating in the Custom Puppy event that players may find more worthwhile. However, there is only a 13-day period between the reveal of the new missions and the end of the Custom Puppy event. Even if players begin the event after the missions were revealed, it is impossible to complete Mission #3, "Drink 15 Groovy Smoothies and Obtain a Custom Puppy Tail", which requires players to log on for 15 days. Thus, players who initially chose not to participate in the Custom Puppy event now find themselves locked out of rewards that they didn't even know about.
A simple solution would be to extend the Custom Puppy event, perhaps by a week. This would allow enough time for players to complete the mission even if they start the event after learning about the Maple Missions.
