Trying to input a seed into the coordinate bar for Immediate Surroundings doesn't "stick" / update the line.
To actually get it to change, you have to manually go into Customize, change the world type and enter in the seed line separately.
Steps to Reproduce
Launch Game window. Enter: VOLCA-466878055-0 into coordinates. It doe NOT change to the volcano nor change the seed either. To change it to the correct seed, you need to go to customize and change world type. and enter in 466878055 as the seed to get the coordinates to stick.
