What steps will reproduce the problem?

1. An error occurred when I entered the eternal palace - Zaqul's option, then the option becomes invisible.

What version of BigWigs are you using? (Stating 'latest' is not useful)

v158

Do you have an error log of what happened?

Are you using a custom version of bigwigs? You are missing some files.

I am sure that there is no missing file, and the official version is also used.
Very strange other BOSS's options are working properly and there will be no errors.

I tried to use the old version back, or delete the log file in the WTF folder, this error will still occur, only in this BOSS (Eternal palace - Zaqul), it is really strange.

This error happens because you have out-of-date locale files.
We cannot fix this for you, it is an issue for you to fix.
You can try deleting your BigWigs folders and re-installing it fresh.
