Constant 100% Realtime Peak with Cubase 8.0.20


I updated from 8.0.10 to 8.0.20 and was experiencing 100% realtime peak constantly on a project that worked perfectly fine before I updated. Buffer size and ASIO guard are on the same settings as before on 8.0.10 (32, normal). I recently rolled back to 8.0.10 and now everything works perfectly again. Hoping someone can shed some light on this issue so I can eventually update to the latest version.

Running OS X Yosemite 10.10.1
