Updated in V2.55, I added some paint to show the fishing spots aswell and indeed somehow the game or client thinks there is fishing spots even when there are none visible.
As far as I can see in the code I can't distinguish them from eachother, so i assume the client fails to refresh them or something.
I did add a block for those spots if interaction fails so the bot won't try interaction with them again
Thx for letting me know!
