hopefully I am not being dumb but I had Rapid Recharge queued up to buy but it seemed to be randomly purchased when I was not near a shop

that makes sense but I've tried watching it over including the minute leading up to it and I can't see how. I go from the double sinner's building, to blue lane my side, but there is no side shop as the guardian was killed ages ago. neither I, nor my crosshair goes near the secret shop. I'll try and figure out how to use the spectate replay feature better to look at each shop when I get the upgrade.
