Yes you heard me, a map reset is going to happen because the server suddenly has no storage for some reason, and because of that a lot of damage was caused, so even if we get bigger storage we would need to make a map reset, the damages were that severe.
We will try to let people in the server to save their buildings and their stuff before its too late.
For saving a building I suggest using a schematica mod
https://www.youtube.com/watch?v=SASJVr4ZFi8 a video about it (it works like this for 1.7.10 as I know)
and the link for it https://cdn.discordapp.com/attachments/238040548374609921/351749784316674048/LunatriusCore-1.7.10-126.96.36.199-universal.jar

We are currently doing everything to save yours and the servers important things, please be patient for updates!
