it got cut off when theres a very long LN, you need to make the ln percy image height to be about 80k+ pixel long in order to fixed that, but 40k-65k should be enough, make sure the image didnt get stretched
here it uses percy, i test it on the same map and it didnt get cut off like that, but it still gona get cut on a certain map that has much longer LN, and its normal, every percy has this problem and can't be fixed
