>>49010471Keep in mind there are rules that specifically state 'when you catch', so if the issue was that you rolled Kappa Ambush, it will take place the moment you encounter the Lotad.
In other words, if you rolled the 50% for Torchic and it was fated to die, you just failed to catch its replacement. Which means you have a stock of 0 and just lost your run already.
Fun!
