Some structures generate at different locations

The bug

In the new snapshot, structures seem to generate at entirely different places than previously. For example, seed 1 has a jungle temple at x=744, z=56 in 1.12 which is not generated in 18w06a, therefore 18w06a has one at x=520, z=312 that did not exist in 1.12.2

Structures that are affected:

• Jungle temple
• Igloo
• Mineshaft
• Stronghold
• Witch huts

Structures that are not affected:

• Desert pyramid
• Villages (Layout might be slightly different, tho)
• Ocean monuments
