All lotto reruns are like this

I was so expecting to complete the 100 boxes challenge I set for myself every lotto event :(((

(I had completed none)

Yes and I mentioned it on the guide has well that I posted a day back

Reruns always 10 boxes, if you wanna go ham then new Christmas you can go ham.

Yes

Only the reruns. The original run is probably unlimited.

All lotto reruns have been like this with the exception of the Da Vinci and the Counterfeit Spirits event rerun way back if memory serves.
