In version 1.18 strongholds in chunks that where generated in older versions are not detected.

How to reproduce:

• Open the attached reprod-world in 1.17.1 (player location in stronghold at -7362 30 -4147)
• run "/locate stronghold"
• or leave the stronghold and throw ender eyes
• open the world in 1.18
• run again "/locate stronghold"
• or leave the stronghold and throw ender eyes

Expected behavior:

in both versions the locate command (and the ender eyes) should lead to the closest stronghold at -7362 30 -4147.

Actual behavior:

• in 1.17.1 it works correctly: ender eyes and "/locate stronghold" lead to the closest stronghold at -7362 30 -4147
  

• in 1.18 ender eyes lead to a stronghold at -7784 ~ -1640 (about 2537 blocks away)
