When creating a Current Era in a timeline, the error message 'Current Era cannot wrap around any other era' always appears, even when the date provided would make it the most recent era in the timeline. In other words, the error message occurs even when the Current Era feature is being used correctly.

1. Click the Timelines button
2. Create a new timeline
3. Add a normal past era with any date range
4. Attempt to add a current era using the final year of the past era—or any year thereafter—and press Create

At this point, you will receive the message 'Current Era cannot wrap around an other era', and will clearly see that the date input would not have the current era wrapping around any other one despite the message.
