This happens from time to time with my maps, just be patient and give it maybe a day or two before trying to access it again. FH's servers aren't the most reliable and this causes faulty connections. It's a pain I know- but unfortunately there's no way around it but to wait :/ Sorry for any inconvenience, I hope you'll be able to get back in and enjoy the map soon.
Okay! Thank you for your quick reply. I really enjoy your maps btw. ~
No problem, I'm glad to hear it!
