I can't open the link, I don't have a microsoft account. You need to enable anonymous users to view the link:

nvm, I reproduced it really quickly. Ironically I knew this was one of the last places I could have an error, and didn't prepare for it. edit: huh, this wasn't what I expected

Thanks. It looks like Microsoft changed stuff again. And thanks for the link.

Alright, I know how I can fix it, but I need to ask on the factorio forums if a semicolon is valid in a name. It's not normal, but I don't know if it's wrong. Give me a few minutes to test a fix.

Alright, updated. It doesn't have an error but you'll have to tell me if it actually works.

Ok. I played with it for a few minutes. It seems to work ok. Stack sizes as expected and the other mod works as well.
Thank you for your time.

np, so far you're the only one to report bugs. It means a lot
