Unity. Fonts. How to address this bug?

I wanted to have more of a discussion about this than get an Answers-style response, so I'm making my first (I think) thread in the forum to ask this: why do fonts get broken at runtime in Unity!?

It's not an issue I run into all the time, but when I do, I'm at a total loss how to fix it. I don't know if it happens more often on mobile, but I see it on multiple devices running multiple versions of Android (don't use iOS nearly as much so I can't say there).

And it's not just something I'm doing wrong. I've spent about a month now playing the new mobile Star Wars game (Galaxy of Heroes) and I know it's a Unity game because... sometimes I see this font issue!! EA found a way to correct it after occurring, and I'm wondering if anyone has any idea how. Maybe flushing the dynamic character data (is this possible?), or maybe it's as simple as forcing a redraw on some components.

My best guess at what is happening is this: a dynamic font atlas needs to be regenerated, so Unity should be finding all the Text[Mesh] objects referencing the font and updating to match the new UV-coords (or however this works under the hood), but for some reason a few components aren't being updated.

Does this sound right to anyone? Does anyone have a reliable way to work around it? Thanks!

 

Missing to update the UV-coords of the text sounds like a idea, another could be corrupted memory.

 

Do you know any direction I could explore to detect and/or correct it when it does occur?

It must be possible if EA did it, but I'm also curious how hacky/involved the process might be.
