When trying to run a modded game with FNEI (and bobs/angels) the following exception follows when loading the map:

The mod FNEI caused a non-recoverable error.
Please report this error to the mod author.

I came to post the same issue, I have the same error message.

• Removed label style want_ellipsis as it will be used automatically everywhere as with button.
  From the changelog, this seems to be the error.

I am also getting this issue

Fixed it by removing all occurences of want_ellipsis

im getting the same issue :C

Confirmed, removing all occurences of want_ellipsis will be solved

How do we "Remove all occurences of want_ellipsis" i have a 70 hour save i currently cant start :(

Thx a lot, saved my weekend

I've linked to this conversation in the GitHub repository - hopefully the author will now see it sooner rather than later :)

For future reference reporting directly on GitHub is the best method for the reporting of errors - it's linked directly to the autor's email.
