Hey, I used to run into other pets there to fight/capture. Now it seems like it's empty... I can't afford the Maze atm and am prolly too low of a level any way. But the field was continent for training my fighting team.

Hey! The Festival itself only ran until September, 13th (and that was actually longer than it was originally scheduled for). That's why you can't do much of anything in the field though a couple of the other functions are available until September, 20th and/or September, 27th.

Here's a couple posts from Krinadon regarding this from the Festival Extension thread:

The only thing being turned off at midnight really atm is battling in the explore zone. A week from tonight, the shops will close. A week after that, everything else will be disabled.

Additionally, Maze Tickets are now available on the merchant in the Festival Zone for 1,500,000 gold each with limited supply. From now through Sunday, September 27th, you can continue to access the Maze and spend your Tickets and you can continue to access Sylesti Seeking to use your supplies and create pets. After then, it will be removed and the Summer Festival will be 100% closed for the year. Thank you to everyone who has participated in the Festival this year. We hope you had a fun time! You can look forward to continual MegaZone updates, the Aurleon Revamp, and the Fall Festival over the next couple of months. =)

You could always switch to levelling up in Viridian Meadows and Umbra Forest. Might not be quite as efficient but you can progress the storyline at the same time so I suppose that's a bonus!

ok thank you! I was training there since my team seemed to be to low of levels to progress, but they should be fine now anyway.
