I'll wait for your response
Thanks for the attention

I am unable to duplicate the issue you are describing. The hot-key works just fine during preview. It is generating the building and removing the item from the players inventory.

Wow, thank you for that! I hadn't thought to put the building in my offhand.

I will take a look at this after work today.

Thank you!

This has been fixed with version 1.6.5.2 which has been uploaded to curse forge.

This will be available once it goes through their approval process.

Thank you for finding this issue!
