I play on Xbox One. The graphic bug that I pointed out in the two photos shows up when I use the "Pirates of the Caribbean" mash-up. As you can see from the photos, while I'm fishing, the fishing rod thread is not attached to the rod itself (but remains suspended in the air). Using Minecraft's classic textures this graphic bug does not show up (the thread is correctly attached to the barrel while fishing is done). What is a problem with the texture of the fishing rod included in the "Pirates of the Caribbean" Mash-Up ?? I await your reply.
I monitored all the updates made over the past 6 months on the "Pirates of the Caribbean" Mash-Up and the fishing rod line has not yet been fixed.
