A Problem with the Online Poker Rules (Bug in VC Poker)

[AfricanAnimal]

Ok, so this is what happened, I suspect very strongly that this is a bug but the MANAGER, host MarkW disagrees with me and was rude.

I hold KK, I call UTG for $1, UTG+1 raises to $4, Button raises $1.54 All-in. This is where it all goes wrong, Under Raise rules come into effect and they stop me from reraising the original raiser UTG+1.

I still won some money off this, but not as much as I could have. But these Under Raise rules should not have come into effect until after my go (assuming I wanted to call) and if I raised, then not at all.

What do you think?
