It was worth trying support, however I did think they woudnt help, and it appears that it was somewhat mean of them not to,though they were right to say that your friend should have checked before the final decision, as the game has several areas where there appears to be what are deliberate traps for the unwary to fall into.
The most obvious is the spending gold accidentally,beacause of its proximity to build,train,and research buttons,it also uses the same space as the purple free button.
Another is the free novice jump button. which changes its usual order when moving to another kingdom for clan events.Theres probably more.
An undo mistake button would help, but how often would it be needed to warrant its inclusion.
Dont know how many Drakkars he spent but they couldve just moved him,or given him the Drakkars needed to move,but unfortunately the
innocent suffer the consequences of those that would abuse the system.
Which is probably why they didnt help.
