Just to give some information about the status of the issue from our side:
We have shipped some pcbs to china, to the mold manufacturer. I talked with the mold designer today, he got the pcbs and he is going to work on determine the issue (yes, we know its on the spacer but we need to know whats failing on some consoles while most work fine)
Its chinese new year now and i dont know when he will report back, as soon as he tells me where the issue on the spacer is we will decide what to do.
My recomendation for now is : mod the spacer as its an easy mod, if you screw the spacer while moding it, we will send you another spacer (like the current one), thats not a big deal to damage the spacer.
Again, sorry for the inconvenience.
