Just downloaded the update (so excited, by the way!), and after a couple rounds, I kicked an enemy into the wall. It was able to pass back through, but I feel like this is still worth mentioning.
This was on the "Death Cube 2.0" map, if it helps.
I ran into this during testing and made it a file. You found this issue quickly today, so perhaps its fix will now get a higher priority. Thanks for the report!
