Yes, I am amazed that quite a few people in this thread are saying they 'had to completely reinstall the os' and that it broke everything after not much time. As long as one doesn't rely on the AUR for system critical packages or much in generel, it is incredibly hard to break an Arch system (Manjaro and other Arch-based distros don't count). This is due in part to Arch being quite reproducible but it also having very good maintainership.
It doesn't hurt to apply new package configs by going through pacdiff once in a while though.

I see no one has mentioned Bedrock Linux yet. Not sure though how others would rate its 'obscurity' though. It's definitely a standout among distros.

KDE for its Wayland performance and features and occasionally I switch to hyprland if I need a more focused work environment.
In the past I used Cinnamon but it became ever more buggier on Arch and due to lack of Wayland support still it was a dead end anyway.

Regarding your question, you can just clone the package's git URL or download the PKGBUILD file directly, make your edit and run makepkg or makepkg -sirc as the wiki suggests to produce the package and install it.
You can also install the package tar with pacman -U <file>.

But looking at the comments it seems you are using an AUR helper that has a cache you might want to clear as the git repo for that package has an unstaged change for the license file for some reason (or you reset that file so git doesn't complain when pulling).

Edit: I see you figured it out already.

I created an account there an eternity ago when I first heard about them to reserve my username just in case but I will never consider a platform that cannot package their launcher/tool/software correctly and instead shoves a complex curl-to-bash script embedding binary data and a whole lot of other anti-pattern up my throat that is the least trustworthy and safest method of distributing your software.

Well, Minetest also can hardly be compared to Minecraft as Minetest is only an engine or platform for voxel based games like Minecraft. What you rather have to critique is something like Mineclonia that is apparently a more active fork of the MineClone2/VoxeLibre project that try to perfectly replicate Minecraft (without using Minecraft assets that is) on Minetest. Allegedly it's pretty good now but I haven't tried so myself. As already mentioned, the community for Minetest as a whole is pretty small and that additionally split among so many different games building on that. But it's good that viable alternatives exist in case Microsoft ever considers shutting down the Java edition.

I now just use EurKey (Qwerty) with a very nice Alice (Arisu) keyboard. If that was all I was using I would probably try the eurkey variant of Colemak(-DH) at some point.
