I took the time to learn how to edit and compile the missing jar.
I merged both codes with the one Drusvak provided, and compiled it.
Here's the mod (multiple servers just in case):
Also, i edited the mcinfo and added Drusvak as the provider of the double chests, you tyler as the creator, and me as the one that compiled it.
And one more thing, i renamed the version as v1.0.3 for the double chest update. I hope it doesn't bother you.
I don't mind at all, and I'm honestly glad someone took the time to not only compile it but also add new feature
