I'm playing 1.18.2 and I'm sure that's partly responsible for this, but after pressing Finish in the blueprint mode (whether by clicking or pressing the F key) the game freezes, cuts to a "Server closed" screen then crashes shortly after.

I'm having the same issue on 1.18.2.
Composing works, but as soon as I try to finish, the game crashes.

Exactly the same issue here too. Please patch for 1.18.2?

Seems like the repository has not been updated since 2021.
Somebody made a pull request to make changes for 1.18.2, but they have not been incorporated.
I could try to build it and see if it works.

If that will work on 1.18.2 that would be awesome 🚀

YES PLEASE!!!!!

Hopefully someone will update this repository and push the changes to curseforge.
But for now we can at least enjoy this great mod on 1.18.2

Ok, so I tried building the pull request and it seems to function correctly.
I could save a schematic and use it with the schematic table / schematicannon without crash.

For those who want to replicate what I did:

1. Clone the project
   git clone [email protected]:simibubi/TheMightyArchitect.git

2. Fetch the pull request
   git fetch origin pull/43/head:1.18.2-port

3. Checkout the new branch
   git checkout 1.18.2-port

4. Build the jar with gradle
   gradle assemble

5. Copy the jar from the /build/libs folder

For those that just want to download the mod and add it to their minecraft:
mightyarchitect-mc1.18.2_v0.6.zip

You will have to extract the .zip file and put the resulting .jar file in your minecraft mods folder.
!! Please beware. I don't recommend downloading random files from the internet and adding them to minecraft. It's always better to do the build yourself if you can.

Also thanks to @glutzer for actually making the port to 1.18.2.

Enjoy!

Worked Perfectly. Much Appreciated

Felt really stupid since I used the 1.18.2 version but the issue persisted.
If anyone else is experiencing this, make sure your shaders are disabled.
That fixed it for me.
