Strings that use certain fonts seem to ignore the "Messages Freeze All Action" quest rule. I've only tested a few fonts so far, but here's what I got:
Fine:
Zelda NES
Allegro Default
Hylian 1
Oracle
Zelda NES (Matrix)
GUI Font
Bugged:
LttP
LttP Small
Link's Awakening
Small
SS 3
I'll add more as I continue testing.
I've been using the LttP font with that rule, and it seems fine to me, aside from a little trouble at the 72-character mark. It's not working at all for you?
After doing some testing, I think the 72-character mark is the problem.
On the screen with the message, I have a timed warp, so that it activates once the message is over. The good fonts I've listed, when they hit the 72-character mark, just end as if it was the end of the string, and I can press A to go to the next one, and everything's fine aside from that each string is missing several characters. The bad fonts I've listed, once they reach the mark, the warp is activated.
I assume this is fixed by my recent change.
* Fixed a bug where strings longer than 72 characters wouldn't work with the 'Messages Freeze All Action' quest rule.
