Tbh, that leaning tower of plywood sounds like modern art.

On a bridge job in Ohio, our crew once trusted what seemed like firm clay. Matthew's point about point load is spot on, but we learned the hard way that subsurface water flow can undermine everything. We had a 300-ton crane settle unevenly during a critical pick, not from the lift weight, but from a hidden spring we didn't map. Now we always do a quick probe test with a rod before committing to a setup. That extra ten minutes beats a full day of recovery work.

Did they give any reason why it locked onto your shoes? Like was it a sensor glitch or just bad programming?
