Hello! Thanks so much for this information. I was able to write a similar script in my example game and recreate the exact looping error. That should definitely help in tracking down the issue. I'll let you know once I have a fix!
UPDATE: Good news, I have a fix for this now! When determining the entity's rotation, I was incorrectly assuming that the target entity was a character, as opposed to a tile or object. I'll include this in my next release, which should be in the next day or two. :)
