Pronunciation mismatch in Simplified Course

Hi all,

I noticed that a few characters by the end of the Simplified Course seem to have inherited Taiwan pronunciation.

In particular these 3 characters are assigned the pronunciation:

怔 - leng4 - but in Mainland seems to be pronounced zheng1
缚 - fu2 - but in Mainland seems to be fu4
惋 - wan4 - but in Mainland seems to be wan3

I understand that words containing these characters might be unambiguous regardless of the pronunciation, but still believe these slight differences are nice to be aware of :slight_smile:
