Launchpad rearranges itself on startup.
I use launchpad all the time mostly because i like to keep my desktop clean.
There were some stubborn apps i couldn't delete from launchpad so i deleted them using a terminal command.
Since the moment i did that, the apps in launchpad constantly rearrange themselves
but only on the first launchpad page not on the second one,
but on the second map is a folder that does keep rearranging itself.
So i thought maybe i could fix it with moving everything one page further.
Now after a restart the second page suddenly became the first page and vice versa
and the second page is rearranging with the apps from the first page.
Every time i open launchpad it's basically playing games with me. And this being one of the things i use the most it's like a **** nightmare and a loss of time to find everything i need in launchpad every time i restart my macbook.
And emptying my launchpad is also not an option because somehow i can only open some of my apps when they are in my dock and resetting launchpad also kills my dock apparently.
TL;DR: My launchpad likes playing Where's waldo with my apps
