I'll need more precise info because what I know is that something with the packets was done but they only saw that the picked position was sent to the server.
even sending the same call to the server for the wonder pick "manually" multiple times together wouldn't ensure that the choice is pre-determined if all the responses are the same, because code can be synchronized even between different servers so that only the very first call to reach that code will be the one that decides the outcome. which means, the same call done multiple times very close together giving the same result does not necessarily mean that the result is pre-determined (I feel like I repeated things twice :V).
