Unfortunately no way it current update unless you edit some values in game's save data file. It's located in "C:\Users\LordOfSouth\AppData\LocalLow\LAGS\Hailey's Adventure"
Make sure you back up your save file before editing anything. Once you done that, open saveData.text and change "knowsCane":1 to "knowsCane":0 and "caneLost":false to "caneLost":true. This should reset her status allowing you to fight her.
If you don't wanna fight her again, open sexData.txt and change "sugarcane":0 to "sugarcane":1. It will simply unlock her image and animation.
