Lining up (poly)lines using another block corner as a reference

I'm using AC to manage a cable map in one particular drawing. This drawing consists essentially of a bunch of blocks and poly lines. I have blocks that represent ports, and another block that represents a device. The device block consists of multiple port blocks and that combination is, in turn, wrapped up into a block of it's own.

I start a pline, connect it to the port block, wrap it around the hard lines of the port block, the device block and out to another block representing another device. I would start another pline on a port block adjacent to the first one and overlap the first pline everywhere else except the beginning and the end. This lets me highlight each pline individually (or multiple at the same time) and see the 'path' that I've created between devices. This is my cable map.

After a while, what starts to happen is that additional overlapping plines don't actually overlap perfectly along all vertexes. A vertex would usually be created when a 'cable' would need to go off in a different direction. I have the snapping turned on, so I would expect the vertex on the second pline to perfectly snap to the vertex of the first as it overlaps, the third to perfectly snap to the vertex of the second, the fourth to the third, etc.

This doesn't seem to be happening, so I'm wondering if I'm doing something wrong with the snapping, if this is expected behaviour, or if there is a way to tell multiple vertexes to all nicely line up on a corner of a block.

Hopefully this makes some sense :cara_con_una_leve_sonrisa:

Thanks in advance!
