PAT Error - Could not set argument to value 'None'

I am having a very stage error occur on a PAT v2.4 run. All of my runs will complete fine when I run them individually, but when I run everything together (40+ runs) they will fail and give me the following error in the run.log file

[13:16:51.509776 ERROR] Could not set argument 'change_east_windows' to value 'None'

Any idea what is going on or how to fix it? The argument that is causing the error is a true or false, and is set to false image description It is incredibly frustrating because as I mention, if I only try to run a couple of runs or just one run it will run fine.

@TaylorRoberts, sorry that is happening. When you ran the single simulation were you still in PAT or was that in the OpenStudio application? Have you gone into "Algorithmic" model and then back to "Manual"? Lastly have you selected a measure option for each design alternative?

If you zip the project up i'm happy to take a look at it. To prepare to send do the following. Quit PAT, delete anything in project directory except for the following (pat.json, measures, seed, weather, and scripts if you have it). Then zip and send to

I don't have a solution, but I believe it stems from deleting an option and you had previously assigned in a design alternative. While it defaults back to 'None' in the option assignment, it still tries to apply the measure with the arguments assigned as variable having 'None' value.
