Thanks I really appreciate that I actually didn't know there were ways to test it without an ARM system or build it with fewer resources I will definitely have to look into how to set that up for next time. Thank you for the tip!

Also, I've force-pushed the fixup commit for this PR. Let me know if everything looks good to go now
