I have this issue too since some time back. Really old tabs open instead of the recently closed one when doing Ctrl + Shift + T. Doesn't always happen. Seems more likely to happen if you've had the browser open for a long time and been doing lots of browsing.

I'm having the same issue and it's so annoying. Seriously considering switching to another browser.
