I think it be best to not include the requirement of using our bug net because the lag will make lots of people mad.
Maybe somehow use shovels instead? You know just going around town and digging to find something surprising. And instead of ghost you look for graves and dig on them. Since, its stationary, IMO it will cause less anger since there's no chance of missing. And ofcourse it gives you random prizes.
As for the guilds, I disagree with this because anyone can be in multiple guilds so its kind of pointless. I really wish that they could have an option for people not to be able to join other guilds, but idk...
Also, can someone remind me what the events were last year?
