Crashing with mod added. What gives?

[DrNewcenstein]

Made a simple mod that adds a chest of loot to the starting dungeon (gold and picks).
Chest is a new item (I have done this before).

Added Mod name to Plugins.txt

UE crashes at character generator.

Remove mod name from Plugins.txt and everything's fine, except my mod isn't added, as to be expected.

Using CS in folder with remastered Oblivion.esm (only place it'll run except oldblivion folder).
