@Sotaeko I noticed that on some presentation of the bosses enemies, the presentation doesn't have sound or the audio is from another boss (example: Awethros, a Curberus color variant, has no sound on his presentation. The Cosmical Falgon presentation has sound, but the sound is from the Fearnix presentation). In all the cases i encounter, the issue is on the DLCs bosses, as far as i know this issue its not present on the Story Mode Bosses. There's any way to fix it? I try removing the english patched update and re installed a clean one, and the issue was gone.
PD: There's another issue that i encounter on some mission (also on DLCs chapter), when after a mission, there's a scene and you have to choose an answer, but the speech bubbles are missing or blank. If they are blank sometimes the game still let you pick one, but if there are missing you can't continue. The solution is the same as with the other issue, erase the english patched update and re install a clean one.
