This release changes a ton of small things under the hood to make it compatible with DnD5e Fifth Edition System v2.1.5. That new system version made it so almost all fields have to have a default value now, whether it's null, empty or otherwise.
As a result, I had to change, tweak and improve just about every step of the conversion. This in turn means a that there's a huge chance for new bugs to creep in, so I did a lot of testing with dozens of characters and variations to try and squash them all. If you get any errors in the application or Foundry, let me know and I'll do my best to get things sorted.
Aside from compatibility change, I've made some general improvements like handling multi-classing better and making the code more lenient to homebrew texts in some places. I hope you enjoy this new release!
