For some reason, after i downloaded v13 of blockland and i opened the game, all my builds that i built during v12 are gone. I went into the game and went to host my online server. I loaded the map slate christmas, and when i created the game i noticed that the super admin pass had changed from where i left as well as my server name. When i was in slate christmas, i went into the menu, clicked load, ando nly the builds from before v12 were there. WHAT DO I DO?!?! This is terrible, i've been working on an epic build for 3 weeks every day and now its gone! HELP ME!!!
