I must agree with creating your own from scratch -- when spellcast first came out years ago, it took me a while but it is much easier to figure out problems or even enhancements on your own then :-)
Sometimes using another plugin in spellcast when you don't have the most recent version can cause it to crash. Like using Cancel, Run, Autoexec changes, etc. or I've had problems in the past with mine with the 'include' files.
example:
Code
<xi:include href="includes.xml" xpointer="/includes/include[@name='CancelRules']/*" />
If they are pointed to a place that doesn't exist or not set up properly they can crash. Not always but that has caused problems with mine in the past when I was learning it.
This is my current one, but remember I haven't updated it in a while as I quit for about 2 yrs and just recently came back. It has a lot of blank holes in sets that I don't currently use:
