I had this same issue last night as well. I read that it is a problem that happened when charging. But this morning after I had left my controller on the stand it looked fine. Then I took it off and the area of the battery, and battery itself was significantly hot to the touch. Alongside this the charging stand light wouldn't turn off, it had a solid light though and not flashing. After a while it changed from orange to white as if it was done charging but nothing was on the stand.

Hi Guys, 

Flashing orange should only show when in charging status. Please PM me the serial number of your charging stand so I can kickstart a support ticket and help you escalate your concern to the relevant team for advanced resolution. Thank you!

I just started having the same issues as well, though it seems to charge fine. Just flashes when not charging anything
