[Reticulatas]

Fixed:

• SetText not updating contents

Thank you, this was very helpful for me!

For some reason, this version is not working in a packaged build; do you have any ideas? It works fine in-editor, but once I package it, nothing works.

Unsure- usually the reason for these things not working in a package build is due to garbage collection. Editor holds onto the references longer than the real game does and prevents odd issues like this.

5.3.1 Has made things more difficult with various deprecations and changes to the way the system builds. I got it building but now it will link in Windows, but not Mac... I was really only using this for simple stuff like bold and italics, so probably about to just move to the standard RichTextBlock... bit said about that, but I'm sure @benui-dev has better things to do now^^ Was a great plugin while it lasted!
