Put the summary of the bug you're having here

What I expected to happen was...:
When I changed my gamemode back to survival I thought I would be able to break blocks with anything, albeit at a slower pace.

What actually happened was...:
When I changed the gamemode back I couldn't even damage any blocks without the proper tool (except levers, wheat, grass, track I assume because there is no specific tool for those items). It was like the new update had gone into overdrive.

1.(using chat commands) Change your gamemode (online) from survival to creative.
2.Change your gamemode back to survial.
3.The bug is caused
