After I installed the new BDS software like any other routine update, I have not been able to get it to run without crashing. The only time it will actually run, is with a brand new world. 
After transferring all of my world files over to the server, The server would continuously crash.
I originally thought this was an issue with a resource or behavior pack. So I did a fresh install of BDS and removed all resource packs and behavior packs. 
If the server does happen to "start", it crashes as soon as a player enters the game. 
The world file is one that we have used for a few updates, And was just freshly pruned and is now down to 1.3GB. 
Trying to run BDS with a "pre-pruned" world results in the same thing. (Crashing)
PLEASE drop a hotfix for this, As I'm sure its affecting a ton of people. And our member base relies on this server to make its content as work. Thank you!
