registrator seems to no longer exist?

I've been messing around with a server for a while, and now for the past few hours I have been troubleshooting it and trying to figure out why it wouldn't start or why it wouldn't let me in. so far I have solved all those past problems but then found out one of my favorite mods had to be removed because one of it's dependencies just fell off the face of the earth. I had to uninstall and reinstall every single mod manually and that got rid of the required mod which has had it's presence removed from curseforge and modrinth.

registrator is a required support mod for apexcore, which supports fantasy's furniture. maybe apexcore no longer requires the support mod, idk?
or whoever made registrator has suddenly decided to delete it from everywhere and anywhere. I still have the registrator file, is there any way I could like put it into the aternos server mods file so the mods function as intended?

I'm still troubleshooting up to this point with the minor errors and changes that I make that cause it to just completely wall me from getting into the server at all. I'd like to be able to at least add this mod back and be done with it.

thank you i guess we just wait and see
