From the past 40+ trial chambers I’ve seen, not a single corridor exceeds above 29 blocks in length. You used to be able to find corridors up to 90 blocks long (on some rare occasions more) and this would allow you to have a more unique trial chamber experience being able to explore and conquer very long corridor hallways of trial spawners and also allow you to have a true trial chambers experience of being diverse and unique every time you find one. You also used to be able to find 10+ combat rooms, however, now 7 rooms is really rare due to the size of the trial chambers. With the 40+ trial chambers corridors that I’ve found that are always 25-29 blocks in length, the unique diverse experience of trial chambers that are very long with more rooms is gone. Attached below are some examples of the trial chambers corridors in block length now. The fact that every single corridor is around the exact same length leaves me to believe this is a generation bug.
