Actually Saturday was about 1,000 higher than typical, though Sunday was the same as usual.Interesting to note that the steam charts show no unusual rise in concurrent players over the weekend. Which means the very predictable movement of carriers for the CG wasn't planned for or modeled in any way. Or was ignored. Or maybe some entirely different unexpected monster has suddenly appeared behind scenes.
Most likely just the same players doing more carrier-based stuff - I suspect a lot of alts got new carriers this weekend.
