So, I'm running MC 1.7.10, Roguelike version 1.5.0b, and I've created a "settings" folder in my "roguelike-dungeons" config directory. In that folder, I have a file titled "test.json." Here are the contents of the file:

https://pastebin.com/tEfr4WTr

I'm just using it to learn the syntax of the JSON configuration. However, when I go in-game to type "/roguelike dungeon here test" it replies "Failed: test not found." The console then yields these errors.

[12:33:27] [Server thread/INFO] [STDERR]: [greymerk.roguelike.dungeon.settings.SettingsResolver:<init>:79]: Error found in file test.json [12:33:27] [Server thread/INFO] [STDERR]: [greymerk.roguelike.dungeon.settings.SettingsResolver:<init>:80]: null

However, this ONLY happens if I have anything in the theme section of the tower object, other than a base. If I remove the "primary" subgroup, the error disappears and the tower spawns just fine.

Any ideas what's going wrong in this instance?

P.S. Fantastic mod. Really like it so far.
