Yeah same here. If you look at some of the tracks you can clearly see they are using the "wind angle lock" feature. You can see some smooth rounded tracks while a good amount of other tracks you can see the straight lines and sharp turns.

What ive noticed about the pro sails is you can blow out the spin or code 0, then hoist the regular sails, sail for an hour or so and then reuse the pro sails and everything will work good. No need for a repair kit if this is all it takes.

I am not sure if its a bug or not, but im doing this and it works wonders.

Started way back in the deep 15K position soon I will be in the top 1000 which is good considering the size of the fleet that is roughly 30k+ deep.
