Problems and warning with multiple tags with same ID #93

Hi, I have a problem using individualMarkersNoKinect. In my case there are multiple tags with the same ID, 4 of them, one of each side of a cube. I get a warning repeatedly with: _TF_REPEATED_DATA ignoring data with redundant timestamp for frame ar_marker_1 at time 171,390000 according to authority unknownpublisher

I think the cause is having multiple tags, do you know how I can get rid of this problem and what is the best way to consider multiple tags with the same ID? Can bundles and multi-tag node used in this case?
