Clash of Clans syncs almost in real time, but it doesn't tell you that you have disconnected from the game the moment you disconnect from the game. Starting at the disconnection time, Clash of Clans will attempt to reconnect. If it doesn't connect in a specific period of time, it will give you the error message. If you exit the game before re-connection, it wont save the changes. You may disconnect from Clash of Clans but still have a stable connection to your Wi-Fi or data. Before exiting the game, I always find a multiplayer match (because that requires a connection to Clash of Clans) then exit the game to ensure that my changes have been saved
Most units that do not have any favourite target, such as barbarians and archers, go after the closest unit/target. However, units that have specific favourite targets, such as giants and balloons, go after their favourite target before moving onto the rest of the village when all the favourite targets are down.
However, it is useful to note that ground troops are affected by the precense of walls. Melee ground units would normally destroy everything outside the walls before attacking the walls themselves, unless there is an opening in the walls. However, ranged ground units are not affected by walls unless their targets that are hidden behind walls are outside their range of attack. If their targets are out of range, then they will just ignore the target and move on to the next nearest reachable target in the surrounding area.
Air units will not be affected by walls as they can always fly above them.
With Giants and Goblins, it gets a little more complicated, we should all know that after spawning units go after their nearest favorite target. Once that building is dead, they then go after the next nearest of their favorite target. But what happens if the nearest favorite is behind a wall? Well then the units need to decide which to go after. This is dependent on distance and how hard the closest target is to get to. The units will prefer to go after the close one, even if it has to kill a wall first, if the father target is more than roughly 15-20 steps away. Both Goblins and Giants operate exactly the same, except for their target. Balloons operate nearly the same way except for the fact that they are not affected by walls.
Healers are unique in the sense that they heal instead of damage. Once they locked on to the nearest injured ally, they will not stop healing him/her until either he/she is dead or fully healed. After that, they will go to the next nearest injured ally, regardless of what threats there are, so naturally air defences are a killing blow to them. They also have AOE effect of twice that of a wizard tower and half that of a mortar.
For wall breakers, they attack the nearest wall. Additional wall breakers placed after nearest wall is destroyed continue in a straight line past the destroyed wall, allowing detailed aiming at inner walls of bases. Here is a table showing how many wall breakers (of a given level, y axis) it takes to destroy a wall (of another given level, x axis)
Hope this helped :)

No since a three star means the damage done is 100 percent. This means that your attack will be equal to or less than the damage done to that base thus not affecting the percentage. The percentage is based on damage dealt per base not per battle.
