Hello everyone. I got to the game Resident Evil 3 (2020). In the last mission, where we need to create a vaccine, I collected the necessary ingredients and went to make a medicine. And then I accidentally put only antibodies into the device, forgetting to mix them with the amplifier. To my surprise, the device gave me a vaccine. And I was thinking, because the amplifier is much further away than the antibodies. If the vaccine is given without them, then why run and waste time. Alas, I overwritten my save, and I can't check it. Please check if this is how it works.

You might have made a mistake on your part. This has been tested thoroughly and there is no bug where the game will give you a vaccine with only one of the ingredients.

Also general rule of thumb is that if you find a potential glitch/exploit/skip, it's your job to replicate it and record a video demonstrating it rather than telling others to do so.
