Thanks for reporting! This was already fixed in v0.13.2. There were a number of breaking changes in v0.13.0 through, so the update might require some adjustments. Let me know if that works for you!

I am using it in your blog-os tutorial and one of the crates depends on 0.12.3 am not sure which one though.

Try using cargo tree to find this out
