Nothing that cannot be solved by common sense. Yes, things might require more advance thinking and planning as the game is tweaked, but that is the way one should play anyway.

Never place a portal out in the open. It should always be enclosed by a building.

Never build a portal or building without keeping a workbanch or fire inside the protected area to keep spawns a reasonable perimeter away.

If you should respawn back in your base or other location and an event begins, run away until you can get some cover. The event will only end when you return to within the event red circle. So moving in and out of it as enemies pursue will eventually run down the clock and end it.
