Yes.
- I’ve been playing for over 2 years. EVERY release has had issues, the bigger the release the more issues.
- To their credit: the developers have always resolved almost all of them in a short time frame from 1hr to as long as two days. This includes Kingdom/Event/and patches.
- Not to their credit: There is no way they have a proper test environment, and I don’t know if they will ever build one.
- If you can live with some weirdness every new Kingdom release and client update for a few hours to a day, keep playing.
Be under no illusions, 3.3 next month will have issues.
