I don't want to compare their implementation methods of this new cache type to their now deleted challenges, but one similarity has struck me already which is that it has been released unfinished, it is flawed, and so implemented poorly once again. Viewing of found lab caches on other peoples profiles is only working for some people. Here is one example of someone's profile who has found some. I can see that there are seven lab caches, but I can't view them.
Well found. I can't view the seven lab caches either
