SOS

I get this error, sometimes. I haven't really been able to figure out what procs this error and crashes the API.  Most of the APIs I am using are from the library, this is for a brand new game that I just started.  I am not a scripter, so all of these are publicly available scripts that I have made no changes to.  Any one have an idea for what could be causing this or how to fix?

It looks like as soon as I click a saving throw for an NPC, this error is triggered

HitDiceHelper has been implicated in a couple of crashes recently, so I'd disable that and see if the crashes continue. If they keep happening, and it is related to saving throws, it makes it easy to test. The following works most of the time: Disable half of your scripts, then test a save. If all is fine, the error is probably in the other half. So re-enable half of those you disabled, try it again. If the error happens, you know its in one of those you just enabled; if not its in one of those still disabled. Keep testing till you narrow it down. Once you know which script is causing the crash, we can figure out how to fix it.
