Affects 1.16 Release Candidate 1 (or 1.16). The dungeon should overlap the stronghold.

[[Helper] gaspoweredpick|https://bugs.mojang.com/secure/ViewProfile.jspa?name=gaspoweredpick] the coordinates provided no longer works for reproducing this bug in 1.16.2
Alright I updated the seed and coordinates, and put them in the ticket:
