So with Creative crashing often due to plots that may not have updated correctly from the transition from 1.13 to 1.14, we are planning to roll back the Creative server to 1.13 and try the update again. Creative will be down during this period of time and will be back once Clowner has the time to deal with the situation.
Just a fair warning, since we will be rolling it back some progress you may have made may be lost, but we will try our best to keep any builds that have been made since the update.
We cannot give an ETA for the fix, but we can hope that updating it again will fix the issues that have been caused.
