Go into the extended settings of your digital keyboard and find the "Suggest Text Corrections' option. It will say something like "no language selected." Click through the option to disable it.

The recent update really slipped some kinda automatic Grammarly bullshit into the typing program. If you've seen a green underline in your text, that's what it's from.

It was doing a bunch of weird shit to the code of the gamefaqs text box. For me, it made quote blocks impossible to post by transforming them into a different format, added a huge amount of spaces/line breaks repeatedly, etc.

I disabled that option and it fixed everything. Just wanted to put it out there in case I'm not the only one.
