I was trying to complete the final achievement "Use all 9 motorways in one game" with today's daily map, and I ended up falling short by one motorway. The bug is that on the final two Sundays at the end (as well as one Sunday in the middle), I did not receive my normal weekly upgrade. For the one in the middle, I ended up receiving a double weekly upgrade on the very next Sunday that made up for it, but I never received anything in "make up" at the end, so I went the final 2.5 weeks of game time with no upgrades, and I ended up having to award myself the achievement externally due to my time wasted.

Another weird thing is that during both times (the 1 week in the middle, and the 2.5 weeks at the end) where I was waiting for the delayed weekly upgrade(s), the game's cursor was not working correctly and I was unable to delete roads or connect the driveways of new houses to my existing road networks. I literally waited months for this final achievement and then the game didn't even play correctly when the opportunity finally came...
