Latest build doesn't load the textures for the alchemical chests and their GUIs.

You are probably on Linux, which is more strict with case sensitivity than Windows. Fixing this now.

The texture names in the current repo dont exactly match the texture names defined in Textures.java

Texture Names:
"alchemicalChest_Large.png"
"alchemicalChest_Medium.png"
"alchemicalChest_Small.png"

Textures.java:
"alchemicalChest_large.png"
"alchemicalChest_medium.png"
"alchemicalChest_small.png"

I'm not sure what would cause some people to see the textures and some to not, but there may be some instances where the texture lookup is case-insensitive. In any case, it's probably just smart to change either the texture names or Textures.java so they match exactly.

Edit: I'm getting these names/code from the master branch on the web, not my local code base

Loads just fine for me using the latest commit. What commit is your build from?
