Oil spills generate during decoration instead of before #4002
@LordGolias normally I generate random worlds (and explore for about a minute at max render distance) until I can see an oil spot that needs to be fixed. Then, note down the coordinates and turn them into a teleport command (like "/tp AlexIIL 345 98 201") and just paste that command in every time I regenerate the world (usually by doing "re-create" rather than "new world" as that keeps the seed the same).
Alternatively you could add a system.out.println statement to the spout generation code to tell you the coordinates every time a well generates.
I don't know of a good way of forcing the player to generate near an oil well, other than increasing the gen rate by a huge amount.
