Default Excess Tween 20 in library for HiSeq

I recently prepared a library using the Multiplexed Shotgun Sequencing protocol (citation below) and sent the library off for sequencing on Illumina HiSeq. The library that I submitted was supposed to be at 10 nM in Qiagen EB buffer supplemented with 0.1% Tween 20. I received word that the library had failed to cluster on the flowcell.

After reviewing my notes, I noticed a large mistake...I added about ~100x too much Tween 20. The final solution was 10% instead of 0.1%. I have a feeling that this is probably what prevented clustering on the flowcell, but I can't find any conclusive info. Does anyone know if excess Tween 20 would interfere with HiSeq?
