There was a mistake in the line at
c236p12, it was supposed to be that Suteguma was already sold. It's been fixed!
About the "that time" line, I can confirm there's no translation error. It's probably one of the things you speculated.
For Robert K looking foreigner-ish, I don't know if it'll ever be explained, but one guess could be that he's actually a step brother and they have different mothers? That also could've contributed to Suteguma being sold/treated harshly by his previous family. Also, the "blond" hair might not actually be blond, I've seen in other series where characters with that hair end up being colored brown/blue/pink, even though it really feels like it should be blond. Baku himself has a similar style, but his hair is white. (Random fact, Ranko's hair was shown to be blue in the OVA.)

Batch will end on next chapter!

I'm really liking the fight too. Lots of small interesting interactions, like Robert K talking to Douji mid-fight in order to get him to confirm that Kakerou & the Developers aren't co-operating yet, and also to stall for time for the developers to come. Robert K really reminds me of Caracal or Hal fighting.
@Jonui
I think the reason why they had referees enter illegally, was because they wanted to beat Baku/Lalo/Hal to the island so Kakerou could scout the island first. The three players were already entering legally in the fastest possible way, as soon as the match began, so the only way to get ahead of them was to do it illegally.
But yeah, I do wonder why Ikon is even wearing a vest. It seems to be more detrimental if anything, since the stun feature it has was shown to be strong enough to even take out Marco. It doesn't seem to be useful outside of actually participating in the game's battle system, but I really don't expect Kakerou to be trying to level up themselves... probably? Unless it's needed to follow the players or something.
