Yes, this is a BUG. Like the title says, the location for Link's jumping tiles while using the Roc's Feather (2.11 beta 15) are HARDCODED. Sure, you can change their locations, but when you close the editor, they go back to their original locations. O_o I'm a BIG fan of the Roc's Feather, so I can't imagine the thought of making Realm of Mirrors without it AND the Spin Attack now that we have them. Please, fix this ASAP. I don't want to have to take the time to move EACH AND EVERY TILE that Link uses for walking just to be able to show the Jumping graphics correctly! O_o
Link's Tiles for Roc's Feather Jump hardcoded
These have since been made where you choose your tiles.
