Realm Of Light Iv Quest Unfinishable?

I recently attempted to do Realm of Light IV and when I reached the very last part of the quest, right before I was supposed to enter the tunnel at the base of the Guardian of the Forest something glitched. Now, I can no longer see Lari and there is no tunnel or portal or anything. I don't know how to fix this. Any help would be greatly appreciated because I have tried everything I can think of.

Figured it out very quickly, but leaving this up in case someone else has this problem. Just run to the Gateway of Light itself at roughly -1042 73 -4352 and you will gain the quest completion.
