Game crashes when attempting to use the starter house prefab: https://pastebin.com/RERyUmYS
This only started happening after updating to the latest version of Prefab, it was fine before that.

Same here 1.14.4 minecraft with prefab-1.4.0.16 if crashes when i click right click instantly even in new worlds previous version prefab-1.4.0.15 working normal and no crashes so its issue with new release from some reason

Sigh, no good deed goes unpunished. I even tested some generation. I will look into this immediately.

Fixes have been uploaded to curse forge. Closing issue.

Again; thank you for reporting this issue and I am sorry that you had too!
