Frederick, thanks for the input. A bit overstated about WP as a whole. SEO is dependent on the theme developers and WP on its own does a good part already, except for the performance bit. I find it acceptable, but I don’t deny that it can be optimized further.
Regarding this issue, I think it’s simply caching configured in a way it’s not updating certain information (provided from twitch) often enough (that information comes from options). I’ll get a local set up and will try to play with combination of both plugins. Must admit, I lost hope before trying to set it up for my own sites, where occasionally blank pages of death would occur because of some issues/conflicting plugins and disabling w3tc solved the bit.
Again, really appreciate your willingness to address the particular issue. I’ll try to do some homework on it first though.
