It says that I have submitted an IL run for this game but I have never done so. What's going on there?

My guess would be that there was another user before you named “jacks” to whom that run belonged.

The ILs were added recently based off of Cyberscore on behalf of the original submissions, but because it is such a simple name they likely just messed up. If you message a mod, they likely would remove it. Though if you are the same person who submitted ILs to cyberscore, there is no need to do anything.

I added a bunch of IL runs from cyberscore to here, didn't look too hard at confirming usernames which is my bad. If it's not your run, I can remove it or edit it to dissociate it from your account.
