Hi DS_EPC,
Greetings and welcome the Community Forum!
I see you're having trouble with the Build Items process not moving forward. Since it was working fine before, it might be a glitch or an issue with the settings or data. This can also happen if there isn't enough stock for the items making up the auto-build item, but you should still get the window to build or buy those items. Have you tried clearing your AccountRight cache? Sometimes, clearing the cache can fix issues with the software not responding as expected. I've also applied a fix script to reset the file.
Feel free to get in touch if you need more help.
Cheers,
Princess
