So whilst playing Gaminglight and purchasing the Tac-Insert. I've been using it fairly often, Now the thing is I've been warned and nearly banned for some-what "Exploiting" this.
When you leave the game with a Tac-Insert placed, It will remain there for a given time before destroyed. And with that, The new tac insert placed will actually stay there until destroyed.
Now these may not function as "Tac-Inserts" However but Shock seem to get some-what angry when they destroy the wrong tac-inse
