Everyone can lose their temper sometimes and there's no need to make a problem out of it. My opinion has not changed and I have the right to express it without offending anyone.The construction has become too complicated, they will simply build less.I have a dozen drawings from the old version on the server and so far there are no problems.
Keeping a civilized tone should not be an issue for you then.
If you think it's too complicated you didn't learn enough. That's my opinion and it's based on experience with other players that had the same issue like you. But most listened to the support r of the community and learned from it.
Building works not much different from planks and beams in unity. Just the pivot points are new and that there are no static blocks anymore, which is a great improvement.
It's my opinion. If you and your players are not willing to learn, better look for another game for you. That's better than "losing temper" and blaming this game.
