Interesting, I just re-downloaded on a separate machine and got the two endings. I'll make a bug note and see if I can fix it. Honestly you got all the good endings already.
Thank you for playing and your support / feedback! You are awesome.
For full clarification: you paired the whiskey with the weed, and water with weed?
Perhaps there are 2 options during the water fetch quest at the supermarket that could be paired with weed?
Thank you for playing; glad you enjoyed it!
