My dad and I play local all the time and randomly it has his player go completely invisible. It doesn't show his armor on or anything. He isn't "invisible to enemies either, just me. We've tried restarting, having him log in and out, and using the copied version of our world. It randomly does it and I'm not sure how to fix it. It's frustrating because we play on survival and I get tired of killing him off and on. It also doesn't show the defense stats of his armor being on. Plus we have the latest update.
