Trespassing warning is missing before Underground Facility guards turn hostile
Tracked since 7 Sept 2026 · Last researched 7 Sept 2026
Problem
An Underground Facility can fail to show a trespassing warning when you do not have permission to be there. This can also happen after you turn in every mission that gave you access to the area.
The guards can become hostile once your permission is gone. CIG says guard hostility should begin 15 minutes after all missions for the area are turned in, even though the warning may be absent.
Applies to Alpha 4.10.x LIVE · Current
Current conclusion
No reliable fix is confirmed
There is no reliable way to restore the missing trespassing warning or regain permission once it is gone. Leave the facility promptly, even if no warning appears, and treat CIG's 15-minute window as an upper limit rather than guaranteed safe looting time.
What not to try
Do not wait for a trespassing warning
The warning may never appear. CIG says guards can become hostile after your permission ends, so leave promptly instead of using the published 15 minutes as guaranteed looting time.
Boundaries and evidence
Use this page when an Underground Facility fails to warn you that you lack permission. A countdown that appears and ends early, permission lost after dying and returning, or hostility at a Distribution Centre is a related but different problem.
CIG still lists this problem for Alpha 4.10.x, but it does not identify the exact affected hotfix, locations, mission types, frequency, or fix date.
CIG says you should have 15 minutes to leave after turning in all missions for the area. A recent report from a different facility type describes guards turning hostile before the displayed departure period was usable, so do not assume the whole window is safe.
No current Alpha 4.10 player test was found that measured whether prompt departure always prevents hostility, and we did not reproduce the problem ourselves.
