Thank you for your bug report, I will be closing this thread as it's gotten off-topic. Please remember to stay on-topic with extra details regarding the bug instead of a gameplay discussion.
Often recently when subbing in for a a disconnect/abandon my game will start lagging and likely crash shortly after. Typically a full on CTD, relaunching then subbing back in however does NOT cause this to happen after the first one.
Sometimes the smart target reticle will remain on target player if you die while attempting to smart cast on them. The big rectangular reticle remains on them until (you) respawn.
