HELP ME! Just one open remaining on chip after CONNECT RING in Silicon Ensemble?

Dear all,

I guess this is a small problem, but how to solve it? I struggled for a few
hours, but did not get through:

I have 1 open remained after CONNECT RING command, before I do WROUTE. Is
there any search and repair kind of function for CONNECT RING? What can I do
to eliminate this only remaining OPEN? Is it helpful to put a
stripe?(Currently I am not doing any stripe, after seeing your suggestions).
Is there a incremental/search-repair "PLACE", maybe redo "PLACE" will help?

I am a little sure that if I put "filler cells", maybe this 1 open will
gone. But I don't want to put "filler cells" because since the circuit is
large, there are a lot filler cells to add, and the post processing, for
example the layout extraction and LVS will be untolerably long... Since I am
not really doing a chip, all I need is just post-layout-extraction
transistor level simulation, so I can leave out filler cell, ...

I don't know how to connect it manually because I don't know where does that
wire connect to... Also that loses flexibility.

Can experts in this group give me some help?

Thanks a lot,
