Hey hey! Thank you for getting in touch :)
Sadly, UI is the only part that doesn't have a set standard size for slicing actually... So unless I'm unaware of another method, you will have to do it by hand :/
No worries, I went ahead and did that! Thanks for the pack, it's awesome!
No problems! Thank you for giving it a try and pointing out the UI stuff. I'll have it in mind for the next pack to make everyone's life easier :)
