Can't zone to overmap. Keep getting "InternalServerError" from loading screen at 52% mark.

1. Title: Can't zone to overmap. Keep getting "InternalServerError" from loading screen at 52% mark.

2. Reproduction Rate: Can't reproduce now as it mysteriously fixed itself.

3. Blocker? Yes, I couldn't play the game as I couldn't access the overmap.

4. Details:
I couldn't zone to the overmap from inside Brittany Estates.
During the loading screen for the overmap, I kept getting "InternalServerError".
This error happens after the "Novia: Building Map" phase and during the "Novia: Coordinating Data" phase on the loading screen, at the 52% mark.
I also tried logging in directly to overmap. No success, still the same error.
I also tried using my recall scroll which recalled me to Brittany Estates (I originally got this error when I was in Novia Market and trying to exit to the overmap).
Still got the same error when I tried to exit to the overmap.

Edit:
I managed to log on to the overmap again. The following details what happened:
a) I tried loading to the overmap directly from the main menu, but got the same "InternalServerError" again.
b) I did nothing and waited for the connection to time out.
c) After waiting for about 10-15 minutes until my connection timed out and I got a [WHEAT] notice from the server.
c) I tried loading the game directly into the overmap again and this time it worked and I managed to access my character on the overmap again.

5. Steps to Reproduce:
When exiting a scene to the overmap, loading screen kicks me back to main menu at the 52% mark with the msg: "InternalServerError".
This error happens after the "Novia: Building Map" phase and during the "Novia: Coordinating Data" phase on the loading screen, at the 52% mark.
