The first entry id(0_e9fpfo0r) plays twice, after that it is ok.
Also, when the related playlist items has reached the last entry, it goes back to the first and keeps on playing that first for ever.
I found out where the problem line with that:
in updateTemplateData function:
if ( this.viewedEntries.length <= data.length ){
should be:
if ( this.viewedEntries.length < data.length ){
any suggestions on the first problem?
