I had the same problem. Here is how to solve it:
Go to following folder:
YOUR_HONORBUDDY_FOLDER\Routines\Singular\ClassSpecific\Mage\
Inside this folder there you can see a file named: "Common.cs" -> open this file with Notepad.
Go to line 90 and add following:
private static readonly uint[] MageFoodIds = new uint[]
{
80610, // THIS IS WHAT YOU HAVE TO ADD!!!
65500,
65515,
65516,
65517,
43518,
43523,
65499
};
The id of the food is 80610, so if the bot does not check for it he will always try to cast.
