Notes for me.
You shouldn't mess with SQL directly while the servers are running, the DB server caches a lot of data and it could cause problems. The proper way to export and import characters is using
bin\dbquery.exe -getcharacter "Name">file.txt bin\dbquery.exe -putcharacter file.txt
This also ensures you're getting all the data in the entity container, which an external tool might miss.
Always run /shardeventstop first to be sure no other event is running. Then
for Halloween: /shardeventstart scriptdefs/Halloween_11_Event.scriptdef
for Winter: /shardeventstart scriptdefs/Holiday_11_Event.scriptdef
for Valentine: /shardeventstart ScriptDefs/SpringFlingEvent.scriptdef
For Nemesis invasions: /shardeventstart ScriptDefs/NemesisPlotShard.scriptdef
To stop an event just type: /shardeventstop
