We ran into an issue where an animator had accidentally typed in characters that were not rendered at all in Spine Editor and caused issues on the game side. For example, if you type in ä, ö, å, they don't appear at all. Another option would be to just ignore those characters altogether while editing a text value.
We noticed this in version 2.1.27.
Would be nice if this could be fixed one way or another to prevent future mistakes. Thanks!
