Fix infinity move to attack action
There is a synchronization error with the client and the server while moving that can cause the client to be a step further than the server.
That cause an infinity loop packet between client and server (client asking to attack because in range with an enemy - server refusing because it’s not really the case) -> in server, moving from cell 149 to 150, client asking to attack at cell 150 (server think the client is at 149.9) then server reset the position to 149 (instead of 150).
Add a small delay to ensure this problem can not happened
