typing /ss in game will force the server to take a screen shot of every player's point of view in game. its main function is to identify someone possibly using a map hack without them ever knowing they took a screen shot for you.
it won't give you the information you were wanting (having him click his smith and take screen shot of it)
the 2 simplest ways to accomplish something like that is either run insight and then you can replay the game yourself
or pause the game > type /ping > take a SS of the /ping info > enable chat for all players > ask player for specific type of screen shot you're seeking "ru.boss click your smith and take SS please" > take 2nd SS of you asking player for SS
then you have all of the ammo you need to get actions taken if player doesn't take ss.
ru.boss's other name is well known. he's a top player with good u.c., timing, situational awareness... his only downfall is that he's mildlly retarded.
i cant say for certainty that there was no suspicious activity.. but objectively it does seem very unlikely.
