🐛 Bug Report: No Pet Causes Adv To Crash

[Willard21]

👟 Reproduction steps

Have no pet (due to starting the game before Pet Rock was introduced, and never catching one). Then run /adv

👍 Expected behavior

Either a level 0 Pet Rock should be granted automatically upon realizing no pet exists, or /adv should account for the possibility of having no pet and not throwing errors.

👎 Actual Behavior

An error is thrown and /adv fails.

💥 Error message

TypeError: Cannot read properties of undefined (reading 'disabled')

    at originalCommandRunner (/bin/src/Bot.ts:121:18)

🎲 DRPG version
