Navarro, I'd be shocked if moving the template for the project box makes the error go away. I'd be willing to bet that the error is triggered by the combination of the template being found on the profile (regardless of where it is located) and no project account on the trusted list as manager.
The amount of work created by changing the rules to require project management when the template is used is something that is unreasonable to expect members to go back to long finished work and make changes, either to add the project account as co-manager or to replace the template with a sticker that, as you point out, often doesn't even exist. The way this transition needs to be accomplished is to:
- Create a sticker for every project that has a template
- Set EditBot to find profiles with project box and no project account as a manager
a. If the trusted list is completely empty then add the project account as manager
b. Otherwise change the project box to the sticker
