Infestation is hard to take part in

fo76 how come the infestation is cleared out before my character has ever finished loading into the event?

The Bethesda answer:

You are missing out on the action because the new Infestation events are being completed in as little as 1 to 2 minutes by high-level players. Once another player reaches the boss, it is shredded instantly, ending the event before your load screen finishes. Because you aren't loading in fast enough to register damage or be near enough to tag the boss, you completely miss out on the valuable 4-star legendary drops.
