Any Chance this doesn't work if Discord Core is also in use?

I'm confused as to what the relationship between this and discord core is. At some point, Discord Auth stopped working for me even though the player can use /auth and gets feedback, including the confirmation that they're authorized, yet the group assignment in oxide isn't working and I have to manually assign groups. to mitigate this, I created a new bot following the discord extension instructions carefully and removed discord core to see if this will work for auth. Please confirm if it's ok to use both discord core and auth or what the requirements, relationship is there. My version is up to date 

I don't see any issues using these together as long as the commands don't clash. The Discord Extension is set up to handle this situation as well. If there are any issues feel free to reply back and they can be looked into.
