Whenever someone guise the power role who check the the guised will saw the guiser name, eg, x guised into y

Cop who check y will have a report saying x is mafia
Tracker who track y who visited z will have a report saying x visited z
Watcher who watch z will have a report x visited z

That is what I learnt in sandbox if im not mistaken

is this fixed?
