I can't tell you how many times a BIAB render has been thrown off by Reaper's importing. Fortunately, it's pretty easy to fix.

First, I make sure the tempo of the project matches the tempo of the original BIAB project. Then I right-click on the imported .WAV file, and click Item Properties at the top.

The fun part is making sure the Playback Rate (in the middle left of the window that opens on the right-click) is reset to 1.00000. Once you've got that for all the .WAV files, you should be good.
