Example of this happening can be found in liquidicechurch.nw on Unholy Nation, specifically in DB NPC "PriestNPC"

If you say
"get married to accountname" the event will invoke 5 times, causing the say2 to read "I am helping (your account name here)", even though it should be attached to you

I know this example is in GS1 but it is happening in the case of GS2 scripts as well.

If you give yourself an Events Team tag and go to unevent_tagteamp.nw, start the game, then use the command "/give ep 2", it will invoke 4 times from the same NPC (a level NPC joined to class unevent_pong"). I also added an echo for the npc.id to make sure it was the same NPC invoking it repeatedly.
