I am currently playing my modpack "Mining with friends" and have included your mod. Firstly, thank you for this great mod :)

I tried a little bit today and unfortunately the game always crashes me as soon as I want to paste a copied structure on a piece of paper in the template. At first, I thought that structures from old versions no longer work, but the same problem also exists with structures copied in 1.20.1.

Here the Crashlog: https://pastebin.com/jm7Zwfd5
Forge: 47.1.3
Building Gadget 2: 0.1.1

I have found my issue. Apparently only old code does not work, and I had overlooked that the new code was not even in my "paste" in the second attempt. New structures (1.20.1) can be pasted. I apologize for the misinformation.

I guess the old templates don't work. That would be my old code:

Can you let me know what’s happening in the template manager when this crash happens ? Is there an item in the top and bottom slot and can you post the paste you’re trying to put in?

It’s definitely on my list to support old pastes :) and I should still prevent crashes with the old paste data either way.

Can you put the old paste data here so I can test with it ?

I don't know why, but Pastebin seems to have just removed the code again -.-

I hope my Github link to the code fits as well: https://github.com/lays24mc/Building-Gadget-Codes/blob/main/Codes/oak_tree_1.json

Thanks! I’ll get working on it shortly :)

Is this your card? :)

Exactly. Thanks a lot :)
