Minecraft PS4 world save glitch?

I went to open a creative world the day after I had a hard time putting my PS4 in rest mode. I was allowed to open the world but was told

Trophies have been disabled because the save belongs to another user.

Also, all of the settings were different, such as it loaded in survival mode and auto save was set to off. Even after turning off fire spread, several fires broke out. I made a copy of the game with the same results. I last played the game on 7/6/15 and the problem was there on 7/7/15. This occurred shortly after the recent update, but had worked fine for several days. Is all my work lost?
