Talk:Grappling Hook/@comment-202.156.10.10-20121019014527

Whenever I press E, whether I have a grappling hook in the inventory or not, some sort of debugging screesn shows up and obstructs my view. It displays information like Solid tiles: 0ms, Misc. tiles: 0ms, Lighting init: 1ms and so on. (Pressing E again dismisses it, but sometimes it doesn't.) It started happening for unknown reasons. Could anyone tell me why this happens and how it can be undone?
