I have recently encountered several issues with the mod, don't know if it they're intended, or are bugs and issues associated with the mod.

(Also note that I am playing on the Fabric modloader)

First, lets start off with the issue with the upper area of the warden armor not animating with the player sneak animation. (If the image isn't clear, I'll be happy to pinpoint where)

Another issue I've encountered, is all the mobs (Except the shrieker worm) sounding very like the player hit and death sounds upon being hit and killed by anything (Including iron golems)

The final issue I've encountered, and I do not know if it is going to be fixed or not cause it is associated with other mods like Charm, Additional Additions, Graveyard, Better Nether and Better End.
The Transmitter is unable to connect to other storage blocks that is from different mods. It only connects to vanilla blocks.
(Again, I'll be happy to pinpoint and show more images if it is not straightforward)

These issues are not huge deals, but I thought why not report them anyways since they would need to be patched or fixed eventually.
The mod is amazing, and I'll gladly continue to lure out issues, bugs, glitches, etc. no matter how small they are for this mod! ^^

First issue fixed in upcoming update.
