They should if you installed the modpack correctly and are using ARK, Aon, or Adder. They are the ones with custom moves programmed in currently.
Hmm, not sure what would be going wrong if you are saying the custom moves are showing up but not the skills. I'll need more info like screenshots of how you are installing things/video, and which characters in question you are using. Discord would be the best option if you are a Patreon subscriber to share info but you might be able to put things here on itch
Are you a Patreon subscriber? Because the VT+ mod you have is meant for the Patreon release of the game (the ReadMe.txt and the name of the file is for 0.1b). If you got that VT+ from the Discord feel free to message me there, otherwise download the VT+ meant for the non-Patreon subscribers (for 0.1).
Once you do one of those things, you do what you did in the video along with replacing the Assembly.CS in the original with the one included with VT+.
