I made a Fighter subclass today, and I'm getting the "This homebrew Subclass does not have the necessary class features with the correct required levels" error. I checked the guide by Stormknight here and saw that fighter subclasses need the features to be implemented at levels 3, 7, 10, 15, and 18. I changed those values to match those requirements and saved my changes, but the error message hasn't gone away. I've been looking through the features I've made and I can't find anything that seems out of order, beyond some mechanical things I may not have written in properly. Anyone have any tips? If Stormknight sees this they seem to have a real good understanding of these things so I hope they or someone else can help me out.

Here's a link to the subclass I made.

There is a glitch that is currently requiring a 5th level feature to publish fighter subclasses. If you keep playtesting and editing pretty soon that glitch should have been resolved and you will be able to publish it properly.
