## Description of the bug
On LV-624, the sand temple stone sarcophagus cannot be interacted with by xenos at all - melted, opened, nothing. They provide full protection and immunity for survivors (or anyone) using them.

## What's the difference with what should have happened?
They should be opened like any other locker.

## How do we reproduce this bug?
1) Hide in a stone sarcophagus
2) Laugh as xenos cannot get to you

## Attached logs
```

Start by locating the LV-624 stone sarcophagus implementation and comparing its interaction behavior with other lockers. Reproduce the issue with a xeno, then verify that the sarcophagus can be melted or opened like any other locker and no longer provides unintended immunity.
