Nice mod, it worked perfectly for me in previous releases of the game, but today I installed aje in ksp .90 and it seems that engine's sound does not change nor go louder/quieter until I completely switch off engines. I've got also a problem with b9's engines (don't emmit any kind of smoke until afterburner, where it looks as expected) I know this is not the place for b9 issues, but it may be related or something. Pd: I don't know if anyone had this problem before, but i searched a little and found nothing.
