Context for executing an Orderbot Grind Tag's "While" attribute.

I have created a c# function that I call from the subject tag to control it's completion. It has been working fine. But I decided to try to add a little extra functionality into it (specifically, to swap in armor automatically for spirit binding) and I have been having trouble getting it to work reliably. I suspect it has to do with game communication timing issues and how the tree gets executed, so I was wondering if there is a reliable way to execute code that interacts from the game in a context like this.
