Hello,
I am still working on it... This is proving to be a really difficult issue to solve and debug in the first place...
For the time being, I have a temporary solution that might work! It's a bit messy, but I understand making stuff work in a certain time frame is super important!
If you set the vertical limit mode to "cut off" instead of "auto pause full", any extra text that's cut off by the mesh will be stored in a variable named "leftoverText". You can take this string and send it back in to .text to emulate Auto Pause Full! You'll know there's no leftover text to show when "leftoverText" has a length of 0!
