Don't know if it helps, but have you tried setting ajaxRound to false in monsterbation options (~line 62)?
if you are using Chrome, press F12 before/after running the code.
when the script shut down, it will produce a console error for tracing, it's good if you can read console, or at least you can clip the console and ask for help.
