To avoid having troubles with Lookup Failures appearing all over your game, use xTranslator to merge the SST dictionary with SeventySix.esm found in your data folder.

for the less-savvy users, please wait a day or two for me to update the mod to the latest patch.

to do this,
1) move the current string folder in data elsewhere or rename it to something else.

2) open xTranslator. make sure its in fallout76. otherwise, options>restart for fallout76

3) file>load esp/esm

4) when the file has completely loaded into xTranslator, file>import translation>SST dictionary

5) select the SST dictionary on your computer. this is the file you download and unzipped in the Update File category

6) in the next screen (apply SST), select "Use FormID references" under Mode (2nd box from the top). click OK

7) file>finalize string. this should save the file and build a new string folder in data. otherwise please create a string folder in data and repeat this step.

your game should now load without Lookup Failure all over your inventory.
