My friend and I keep getting this error when ever we try to join. We have KMP in correctly and the we start to join servers but when it looks like we are about connected, this error pops up and nothing happens. Please help!

We loaded the dev version and now it's working. Obviously you are working on updating it!

Release is only for 0.23.5, Dev is for 0.24. If that was the problem, then you can close this bug ;)
