Is there any way to take back 400 (or more) xmr, that I donated in the game?)
Or it will never happens?) Am I right, that the only way is m to m3 to xmr?
If you converted M3 to M, then you would have to trade it back to M3 in order to withdraw it.
Ok, but what with my lands and buildings? They costs nothing now, but it was the main mony I had..
Any land or buildings you bought should be in your account. It's a free market, so prices go up or down based on demand.
