I have a Bench of four Pokemon and my opponent has GRI Sudowoodo on their Bench. I play Hex Maniac and place down a fifth Pokemon on my Bench. During my opponent's next turn, they Knock Out my Active Pokemon. Do I promote one of my Benched Pokemon before Sudowoodo's Roadblock comes back into effect? The rulebook says that a Benched Pokemon is promoted after a Knock Out before a turn ends, so it seems that I would not have to discard any Pokemon as a result of Roadblock.
