Make sure to remove the tier 2 by reforging once more or you'll be stuck with a non-existing tier2 proc causing a crash on item equip. You can only add traits that can occur naturally on the specific item or you'll crash on item equip, it's trial and error to find out which traits can stack.
When you crash, minidumps and error reports are uploaded to the devs so use your firewall to block ftp access to fatshark.com if you're using your main account. Don't completely block outgoing to fatshark.com cause you'll be disconnected and the game will exit, only block the ftp.
