The team working on DynMap might have finally found a fix for the problem. I'm now waiting for an official confirmation and release before reinstalling it. Hopefully, that should be done within days!

Hi, Apocalypse0.

Thanks for bringing this to our attention. I'm sorry to hear about your account. Hopefully you can recover it somehow soon. :

We'll keep an eye out for your account to login, and I'll try to make sure if the name is changed that we're aware of it.

If there's any changes in the status of your account, don't hesitate to let us know either here in a post or through a PM to any of the staff members!

We'll be looking forward to your return!

Once you get that new account, you can replace your Minecraft username on this page, and you'll automatically be whitelisted on the server. You can then ask any of the online staff to transfer the ownership of your chests, doors as such to you.
