Put the summary of the bug you're having here
What I expected to happen was...:
I was supposed to get the achievement "Sweet dreams" because it says in the description of the achievement "Change your respawn point" and with the introduction of clicking on a bed to change your respawn point by clicking on the bed in version 1.15+, it did not work.
What actually happened was...:
I did not get the achievement even though it says it changed you're respawn point.
Steps to Reproduce:
1. Click on a bed at day.
2. See how it says that you have not got the achievement.
3. ...
This isn't a bug. You don't get the achievement in the day because to change the spawnpoint you require to sleep in the bed.
