I really like this mod, but I have run into a couple of issues.
1. The "auth" command doesn't work. I enter it with the code and nothing happens, the server still rejects commands every time and prints out the "input auth code" query.
2. For whatever weird reason, Terraria uses 4 bytes for the amount of items in inventory, but only 2 for in-world, so any number above 32767 gets broken. Which means trying to use "expcraft" to later convert exp into 100k or 1M items can lead to very sad results, as it drops the entered number of items onto the character.
