"Failed to find string table entry" for only certain entries?

So I solved it like this:

  1. Scanned my blueprint folder for the missing stringtable with path (e.g. /Game/Assets/CommonWords.CommonWords) using Notepad++. BP’s containing the path are listed
  2. Had a detailed look at the BPs to identify uses of any on the key words and updated / removed those manually

In my case, the badly updated assets were either:

  1. Structs definitions (that always have a default value assigned, which in my case was refering to the missing string table
  2. BPs with ‘loose’ nodes refering to the missing string table
