Upon entering two seeds for gameplay I noticed constant errors in world generation including:
Structures not well positioned (with disconnected, for example);
Floating blocks and chunks of earth;
Places where water is lava could enter normally, but physics is not well applied;
Double chests can appear in structures and Even lack of optimization.
Errors in world generation always happened, but after 1.17 or 1.18 it is happening more frequently even with the changes and some corrections in versions 1.19 and 1.20.
Suggestion/Basis of thought: You could review the game code, making it better optimized and applying changes to make the world generation better defined.
Thank you for your report!
However, this issue is Invalid.
Please put only one bug report in each ticket. It is very difficult to keep track of bugs when they are not in their own tickets. Each kind of structure would need a separate report.
However, please review the Bug Tracker Guidelines before creating new reports. Be sure to search for an existing issue as it is likely to have already been reported.
