This same experience (small scale as I tested the process) applies to many popularized processes that have been posted without warnings, or even knowing the risks. It taught me to be much more careful in my build, and not blindly copy others (applied widely). Skill and technique makes a huge difference in the outcomes of many building practices. Advance learning/testing is fundamental, or these days . . . just follow the (well written) instructions.
