There are no glitches - it’s an automatic system based on a 24 hour clock like @NoKittenAroundStudio said.
@Kennyboop Upon checking you’ve taken 5 free patterns yesterday between 08:02pm UTC and 08:15pm UTC.
This means you should now be able to take more.
Please note the limit is for fair usage as we haven’t seen crafters who complete more than 5 free patterns a day. We recommend saving patterns to your wishlist - you can save as many as you want.
Hope that helps
