Crash

Very Important
The bug
When there are multiple dimensions with the same dimension type, the game crashes. When type is a string, it is supposedly a preset for dimension options like ultrawarm, shrunk, etc. However only one dimension can use the default values overworld, the_nether and the_end.
How to reproduce
- Download the worldgen settings duplicate.json
- Create a new world and select the downloaded file when importing world settings
The game crashes because the custom:overworld also used the overworld dimension type preset.
Workaround
Instead of using one of the presets, specify all the default properties like this:
"type": { "ultrawarm": false, "natural": true, "shrunk": false, "ambient_light": 0, "has_skylight": true, "has_ceiling": false }
