Corridor chests sometimes won’t generate

This is hard to reproduce because it will happen at random times.

Steps to reproduce

1. 1 enter a stronghold
2. 2 search for corridor chests ( if none of them is missing, then try the same seed a few time.)

Observed result:
Sometimes a corridor chest is missing, resulting in an empty chest holder and missing loot.

Expected result
All chest should generate
