I am no official, but maybe i can offer you some advice and an explanation about the first bug.
A few more informations would be very helpfull, there is a thread here, which contains information about how to set up a proper bug report:

Mainly, this part could be helpful:
If you play on a speed 1 world, for example , then the first "bug" need not be one. You get greater rewards according to your progress. If you had between 10k and 50k points, you would get 2x4h. If your alliance members had more than 50k points,they would get 3x4h by default, because of there progress.
About the other bug, please tell the player to open a proper thread here with all relevant information, so that someone can help her/him.
