@phpdave11 I have tested this fix and can confirm that it works!
I kindly ask that this PR gets merged as soon as possible.

I should mention that we've been running this code in Production since my bugfix, we haven't had any issues with it as of yet.

I don't have merge permissions, so I can't help you there unfortunately.
