I thought something like that was the case, so I added some stuff in any blueprint in the class hierarchy that was data only but the issue didn’t seem to go away. The UCS function issues, although annoying and have been worked around, aren’t my biggest issue. My biggest issue were the other warnings about not being able to access variables declared in parent blueprints that are present in the original log but not this newer log. The workaround for creating functions to access variable values instead of using variable values directly is only maintainable up to a certain point.
New log also indicates a fun little oddity, saving packages are indicated as warnings. I looked on the master branch of github and saw that this was already addressed, but wasn’t in 4.9.
Did you change your blueprints enough so they’d not only be data-only? If so, did you go through each blueprint that was in your warnings previously? Do those files still show that there is a warning within the ?
This is what I would focus on at this time because warnings don’t always cause a project to fail, they’re just there to let you know that something may have not worked properly:
