I'm having a reoccurring issue placing Walani's surfboard on the water. I frequently have to build a raft, get on that, then place her board to get it to work. If I try to place it while on land, even if I'm placing it as close as possible to land, she just endlessly run towards the water. Don't know if anyone else has had this problem and this is my first time using the forum but I wanted you to know that the issue exist.
Try to put Walani's board in the water from all angles.
