Overset Text Threads Off the Page and Pasteboard

I have overset text I am trying to place on the following page. When I click to place the text it suddently jumps off screen. The pasteboard becomes really extended and I don't see the text box anymore. When I turned on text threads, it shows it's jumped past the end of the document and dissapeared. 

I've made sure Smart Text Reflow is off, I've tried deleting or turning off the character, paragraph, and object styles, I've checked for hidden characters. There's no primary text frame. There aren't frames on the master. If I make a text box and link it backwards to the overset text it flows correctly. I'm using Version 16.1.

I thought I fixed the document when I went through and edited it yesterday; text was flowing correctly, but by evening it was broken again. I moved all the pages to a brand new document and it started working agin, but I'm not sure if that's a fix.
