Help with API Scripts Keep Crashing

Hello! I need help with my API setup. Everything was running smoothly, and then all of a-sudden things started going wrong. I cant track it down to any particular Script, Macro, or even action that causes it. The API's just shutdown after running for a couple minutes. The most consistent way to cause the error is to run the group check API and hitting the "Apply Damage" after that. But even if I get rid of both of those API's the error still appears. Link to Error Message and API's Used Thanks for any help!

The easiest way to track that down is to disable them one at a time until you don't get the error anymore.  If you can find a command that aways makes it happen, it's easier to verify that a particular script is causing it.
