Why can't I beat the Zil in Penny's initial quest?

[AhegaO]

Tried the "Fight Zil" option and it came up with this:

Version: 0.9.022-PUBLIC-ANDROID#2600 Message: penny.short is not a function Stack:
TypeError: penny.short is not a function
at Object.Tl (file:///android_asset/www/content_mhenga.52ea723f.js:1:2246296)
at file:///android_asset/www/main.27aa1c09.js:1:12163295
at s (file:///android_asset/www/main.27aa1c09.js:1:10617210)
```

What is the cause for this?

This is due to the penny.short bug. Another coder has already fixed it for the next build.
