[BUG] Didn't receive adventure island reward

Hi, I went into Forpe but was late to the event by around 3-5 mins, there was no event icon on the map and there was only few people around the island so I guessed that the event had already ended. I left the island thinking I would complete it a later time in the day but to my surprise when I checked the compass, it said that I had already claimed the reward for today, even tho it was the first time slot event of the day and I didn’t even participate in it. Please check on this issue since I’m sure it’s a kind of bug or problem about entering the island as claimed the reward, when it should be checked only if you completed the event as claimed the reward.
