[MrGentle]

Branch or Release
v3.0.1

Game and Engine Version

Describe the bug
Blueprint Mods not loading with error message "Actor for mod '%s' is not valid\n".
Also, when putting the .pak files in a sub folder they're not even considered for loading.

Mods directory
I have 1 custom lua mod with a print statement. Shouldn't impact this.

local function log(text)
    print("[GentleMod] " .. tostring(text));
end

log("Initialized\n")

This is likely to be fixed by #503.
I'll let you know when an experimental build is available for you to test.
