I get disconnected from the server when entering a specific area. There are no redstone signals in the area, just a town that I built in 1.8. Are there any blocks that cause crashes in the new snapshot? Anyone who tried to connect to the server and go to that area (locally or via internet) is also disconnected with similar error messages.

This is the error message:

Connection Lost

Internal Exception: io.netty.handler.codec.DecoderException:
com.google.gson.JsonSyntaxException:
com.google.gson.stream.MalformedJsonException: Use JsonReader.setLenient(true)
to accept malformed JSON at line 1 column 1

And the server log from connecting to the server to entering the affected area:

[10:49:45 INFO]: UUID of player UStinka2 is 93f8cc73-5c78-42e5-afcc-7432d2b81b46

I am not sure if this is isolated to my world file going from 1.8 to the snapshot or if anyone else has had this issue. I have tried restarting the server, restarting and re-downloading Minecraft, etc, and nothing seems to change it. It only happens on this specific world file, I have tried replicating it in other areas and on other worlds but have not been successful.
