Item falling out of level despite being 16u from surroundings

[hemebond]

In the attached map, the armour is 16u away from all surrounding brushes and yet it falls out of the level in every engine tested. Moving it 16u higher fixes it. Moving it half-way into the ceiling also works. I deleted the soldiers but they were also reported as stuck in some engines.

For some reason, on the odd compile it worked even with the armour touching the floor/platform below it.

I tried to check the hull in lightpreview but it doesn't work/show at all.

Thanks. What was happening was, after the hull1/2 expansion, the "cage" containing the armour was a fully enclosed pocket of empty space (the armour point entity was inside the expanded brushes).

There's a question of what to do with enclosed pockets of empty space, that aren't reachable from the void, but also aren't reachable from any point entities in the main playable area of the map.

We fill these pockets to solid in hull0, but I thought we were leaving them empty in hull1/2. But it turned out we were filling them in, so I reverted that.
