7899	"java.lang.ClassCastException when hitting the ""w"" button when drawing a line."	rickmastfan67	team	"Just was normally editing tonight with the newest latest build and this error just popped up when I hit the ""s"" button while drawing a line.

Might be related to the [5358] fix, or I just somehow triggered something very rare.
