I've seemed to have encountered a straw bug. I have straws in my freezer, but when I try to send them, it tells me they don't exist. I've included screenshots in the link below.

Any chance you have a space before the stable number? Or it's copied incorrectly?

It's telling you that stable number doesn't exist, not that the straws don't exist. I'd check the stable number and make sure it's correct.

Turns out the person who commented on my straw forum put a totally different number than what's on their page, but I fixed it now. Thank you!
