I ran across a sector with only one Sentry on the sector list. I thought this extremely odd as they are like nuns...they travel in numbers.

Anyway, I closed in and saw 7 red blips and came across 5 Sentries with either no name at all or just a string of numbers like 77832196 and, a Guardian with no name.
I dispatched these bots and they were replaced by bots with normal/correct names.

If this is a result of the update, please consider this a "no bug".

(Off topic, sorry FM) "Horse with no Name" was America, not the Eagles.

RelayeR: Something like... http://cpga.vendettaweb.net/images/ships.jpg ?
This was taken in, Arta O-6. (Sorry for the small pic, all I had of them)

paedric: you're correct...my bad. I get them mixed up all the time.
stick: Yup...just like that, and the bots with numbers as names didn't show up on the sector list either.

I've also seen it (warning, 1.2MB archive):
