I was reading in the update request manual and it mentioned this:

"The blank instruction means the routing server failed to provide an instruction in this node. The client treats this as a non-audible continue straight instruction, which usually means the instruction the user hears and refers to is the next instruction after the blank one.
The reasons for this are:
There is something invalid with the junction
It could have a short circular segment
Very distorted in some way
There is a bug in the routing server when handling this node.
If the reason is #1, it should be quite obvious and fixable in the editor. If not, it may be #2, in which case you will need to open a support ticket."

What is a 'support ticket' and how does one open one?
