After the release of the patch 9.30, many players had an issue when placing traps. Whenever you or any other of your group put a trap, it used to be shown as an enemy one. That was causing fear among players to take appropriate action and mostly resulted in traps being destroyed.
Now, that won’t be an issue anymore. Epic Games has announced that the update is already available and there will be no downtime at all. Those who want to see the trap colors appropriately to the team should download the update and go back in the game.
We've just released an update which addresses traps changing colors after being placed, an issue preventing some players from logging in, and stability issues.
There is no downtime, but a download is required.

This was quite a fast fix after the release of the patch 9.30, as Epic Games has proven once again they’re aiming to fix the issues that are mostly bothering the players.
