This is a photo of the top PCB of the lrp sphere.
If your tab it is not 100% broken you could try to remove the solder mask layer near the tab in order to create a new sort of solder tab.
Basically you have to scratch the paint on the green PCB part near the tab until you see the copper.
Also note that the center tab probably does not have enough "green area" in order to be repaired using this method.
