similar to this error which has dev reply https://www.reddit.com/r/titanfall/comments/5ews2f/thats_a_strange_error/
no repro, occurred under the following situation:

-crashsite early game, everyone started getting titans (indicated as squares)
-other team had 2 titans moving away from the south spawn, up to the side. they were chased by I believe 2 of my team titans, with another having just dropped around where they were.
-I was on the ledge to the side firing at em, but given my vantage, IDK how many titans were alive when the crash occurred.
-when they went up from the south spawn and to the side, I activated smart core, but then a friendly domeshield blocked my vision, so i went back up the ledge and faced south spawn, hoping to pick off any pilots. it was at this moment the crash occurred, I was in smartcore, firing. IDK where their pilots were or where my team's other pilots were aside from the titans previously mentioned
