Hello! I just downloaded the latest 1.14.3 RM release, and first of all this whole mod is a work of art and huge thanks for it!
The weird thing I found can be reproduced with switching to a players view. You'll hear a constant armour switching noise. That's about it, and considering the mod doesn't render sound, this is not a real problem, but it is still annoying. Fix it only, if the more important stuff is taken care of :)
