I believe I typed in TITLEUPDATE24, selected large biome and unchecked balanced seed
As I see the seeds have changed, I started inputting some older seeds I used to play. One of which yielded the largest mushroom isle I have seed and 4 ocean monuments.
Most of the seed is water, has a few smallish sized islands making for a good survival seed. No structures present, sans the 4 ocean monuments, coords below:
Temple 1: -408, 72
Temple 2: -377, 327
Temple 3: -169, 359
Temple 4: 135, 410
I have not searched for the stronghold or any spawners
a "safe" area (meaning only a drop of a few blocks when hitting stronghold) to dig down to stronghold is on the spawn isle, approx coords 4,109
Stronghold seems to be fairly intact, full library and end portal are next to each other, few chests in there as well.
