In the house chores folder, so => "\House Chores - Beta 0.16\www\img\cursors" theres an index.json file that you should be able to edit with notepad.
That .json file is trying to look for the other files inside that folder. Inside my .json file, when the mouse was BROKEN, it said "cursor1.png , cursor2.png, etc".
To fix it I manually edited the .json file to reflect what the other files in that 'cursors' folder said, which in my case was "cursor1.rpgmvp , cursor2.rpgmvp, etc".
That seems to have fixed it for me.
