Deleting multiplayer from the Unreal engine can save memory

On ABZÛ we ripped out multiplayer and lots of other cruft from AActor and UPrimitiveComponent - dropping builtin overlap events, which are a kind of anti pattern anyway, not only saved RAM but cut a lot of ghost reads/writes.

Your presence inspired me to try to look up what the circumflex on "abzû" is supposed to signify. As best I can tell, it's a marker of vowel length.

I wonder how that came to be used. It's a traditional way to distinguish eta and omega in transliteration from Greek, but it's not at all a traditional way to mark long vowels in general.

(I see that wikipedia says this about Akkadian:

> Long vowels are transliterated with a macron (ā, ē, ī, ū) or a circumflex (â, ê, î, û), the latter being used for long vowels arising from the contraction of vowels in hiatus.

But it seems odd for an independent root to contain a contracted double vowel. And the page "Abzu" has the circumflex on the Sumerian transliteration too.)

"Abzu" is also the Greek onomatopoeia for a sneeze.

I was highly amused to learn that the ancient Greek verb for spitting is πτύω. (Compare English "ptooey".)
