I just downloaded and started using the new TE. I was attempting to update my dogwar terrain so that the custom water tile transitions to regular ground transitions wouldn't have the regular water tile in-between. Well, updating went well, yet when I saved, exited, re-named the files to make the update, then re-entered the TE, the transitions were back to normal.
Before I saved the transition was fixed so that half the tile leading to the ground (beach) wasn't the regular water tile but instead the entire transition to land was the custom water tile. Yet after I saved, exited, and then re-entered the TE it was back to normal. Is this perhaps thanks to new requirements on the tile transitions, or is it a bug with the TE?
