By the way, @77topaz, thanks for investigating the rules - Machine exploring is powerful indeed in finding spaceships/oscillators in rules with long rulestrings, but it tend to be cumbersome if I wish for interesting replicators or just generally novel behaviours.

Those are both fascinating oscillators. The first one looks almost like an RRO of an RRO - an RRO-like structure that doesn't quite return to its original position but instead "rotates" slightly as a whole, it's hard to describe. Visually, it's movement reminds me of that of cyclones. The second one...

There is also a limit on how many hauls the script that commits hauls (it has a short name, but I forget what) can process in each pass it does every five to ten minutes, which may be what causing the X3VI hauls to not get committed because there are so many of them uploaded soon after each other.

### Re: MaritimeLife (B2i34c6cen7c8/S2-i3-q4c5a6e8)

Well, to break it down, "reflectorless" demonstrates the idea of the oscillator being referred to as being of a certain geometry so that it would seem that it should involve an internal object being reflected or hassled, but does not. Thus, the term "RRO of loopability 1" is still valid, but only a...

It's not "fake", it's just "loopability = 1". It still reflectorless, it is still rotating, and it is still an oscillator. The term RRO was originally created to refer specifically to loopable oscillators. To quote Discord user zM, "The whole point of an RRO is that you can have multiple phase-shif...
