Hi there, I do not know if this is a bug report, but up until now, I am not able to seed at all as the trackers are all unreachable. For the `fe80:` I understand those are local, but for the rest I do not know. How to make this work better? is this a configuration issue? (I am on a dual stack lite with private ipv4). Thanks, Raffi

Oof, siege buildings are now purposeful. Congrats.

THANK YOU ALL DEVELOPERS !!!!  You are doing a great job to satisfy the unfortunately small community, which makes your efforts even more exceptional. I love you keep up the good work!
