Hey!
Hm, this is similar to a bug that happened in 1.7 that I thought I fixed in 1.7.1, but I must not have fixed it fully. I think I fixed it for text that was done reading but never tested it for text that's in the middle of reading out. I won't be able to work on this for about 2 weeks or so, so I'm really sorry about this, I think I know exactly what's causing this though, so thank you for pointing it out!
