I am still having the same issues with ping perfect. @%$#ed up world gen and no trader and disappearing POIs. I'm about to just cancel my service and say @%$# it.
Theyre support basically just said it's alpha, you just have to wait for the devs to fix it.... even though this seems to be a server side issue...
I have tried removing all files on my end, and removing all created saves and worlds in the ping perfect files.
It's driving me insane. Bought the server the day a20 went stable and haven't been able able play since.
