Renaming a version breaks the version, and renaming it back fixes it

Steps to reproduce:
1. Set up versions 1.0, 2.0, 3.0.
2. Create a page for 3.0 with any content
3. Rename the version 3.0 to 3.0.01 (or anything different).

Expected result
The page(s) created under version 3.0 keep their content

Actual result:
The 3.0 page no longer knows it belongs to 3.0.01. All pages of the renamed version break and display "There is no content for this version" message inside the page
Changing back the version name fixes the issue, and the content of the page is displayed again
