[MC-44879] Changing Gamemode bug

I was making a custom map and made it to where in the lobby you are in Adventure Mode but 5 seconds after the game starts switch you to Survival Mode. However when I do this most of the time on the client it shows the blocks break but not on server side, unless you use an item that can mine that block for Adventure mode.

Edit: the world I used to reproduce the bug(may take more than one attempt): https://www.dropbox.com/sh/305grtkyjxvyb36/Xz5RCsRfD_

MC-44521 @a, @e, and any UUID references work incorrectly after a player dies. Resolved

Tested on copy of world and after the first use it does not let the blocks break.

I believe I narrowed the problem down to the command block having the command "gamemode 0 @a", but when it's changed to "gamemode 0 {username}"it seems to work.

Have you been using this world in singleplayer or through a server?

SinglePlayer world so far, I do not have a very powerful computer so doing a multiplayer world as well as a client would cause lag and to me not be accurate.

I was unable to get a 14w02c Server running so I tried it with it open to LAN and it still glitched the gamemode changeing
