Was this supposed to happen?

Earlier today I decided to join the beta of this game to see what would be different. When I opened the game the first thing I noticed was that I had everything unlocked and the normal tech tree was completely missing. I thought that was cool and decided to try out a match with a combo I've been working towards getting for awhile. I ran a match, but it was really laggy and the game crashed at the end. I decided it wasn't worth it to play with what I wanted and decided to leave the beta program. The app store told me that I would have to uninstall and reinstall the game, so I did. But I still have everything. Is this a glitch? Was it an update that I didn't notice? Please help me fix this.
