[MUICHAOS] Swords of Chaos - GameOp player editor crashes system

[Ohmz1290]

Module Information
[MUICHAOS]
[Swords of Chaos]
[4.17]

Describe the bug
Inside the gameop menu, when editing a player, if you try to use the arrow keys to move to another field, or if you hit enter in the field you're on, it will crash the system.

To Reproduce
Steps to reproduce the behavior:

1. Open Swords of Chaos module and login as a gameop user. (must add key "GAMEOP" to the user account, /sys addkey GAMEOP)
2. Enter the game, then type "gameop". Must have special permission "player editor" set to on, type "s0" to toggle it on/off. "x" to exit permissions sub-menu.
3. "d" for player editor. Type in a valid user name and hit enter, your own is fine, then "a" to edit stats.
4. Hit enter or arrow up or down, and the system will crash.
5. See crash error

Expected behavior
Normal behavior is for the editor to go to the next field when you hit enter. Up or down arrows will also normally take you to other fields (arrow down for next field, arrow up for previous field).

MBBSEmu will crash with error from the gameop player stats editor with the following:

This could be an error with the FSD as I think the only real template we've ever tested with was MajorMUD's character creation screen. I'll have to take a look at the template used by SOC and see that's up! 👍
