I was playing with a dedicated server and came across the same bug as other players, the game fail to load the subworld and the clients get stuck at 100% loading screen.
Here are the server logs, as you can see in the server2. log the second server crashes trying to save the world data
Server logs
The error thrown at the second server is:
[14:56:44.348] [Main Thread/FATAL] [tML]: Main engine crash
Tip: This is likely a mod's fault. Disable mods one by one and check if the issue persists

I don't know if the issue should be in here as the log also says the exception is thrown by Magic storage mod at the moment of saving the world.
Also I tasted a little and this error just happen the first time the sub world is saved, after that the second server loads well and the player connects correctly. this was tasted by disabling magic storage and then loading a subworld, after that it loads ok even after enabling magic storage again.
