It doesn't matter, all saves from custom maps are as good as gone forever with the removal of mapping. Im just saying, graphics are NEVER a worthwhile replacement for a key game mechanism. Modding is what makes blockland great, and this took away a huge chunk of it.
Do you even read?
The terrains and interiors litterally made everything in the game go slower.
The terrains and interiors made the coding extremely complicated, were ugly as stuff and were just a large obstacle in the road of the future of Blockland. They're gone anyways, so just accept it. They weren't needed at all and on top of all that, I'm pretty sure the saves are still there. People can also still do modding.
