SVN 645 one bug of note
Error with the Super Virus event
Doesn't properly describe the the event. I received this event, and from what I read, it was pay +5K gold for 1

or receive 3

in all cities, well I thought, its only 3

and I'm running 90% Culture, lets rock. (Opp's just realised I didn't scroll down for furthers options DOH!!!, looking at picture )
Well, it certainly rolled me, I lost 4 pop in 7-10 cities, now this isn't a big deal, I've a food surplus of 30-60+ in half of cities, but its a huge penalty if you had a smaller empire.
Other game play bugs;
Deselecting various road and mine types, in bug, won't deselect it in worker actions. Bug options

Work shops and factories are bug options, but industrial plants aren't. On this, with mines as well. You shouldn't be able to replace an improvement, with say a cottage, then immediately build the upgraded version of that improvement. I believe they ALL should start at the base improvement, and be upgraded as cottages are.
Believe me, I'm very ANTI COTTAGE. I don't build them, I pillage at EVERY OPPORTUNITY. But I feel strongly, this is an exploit in game play, ALL IMPROVEMENTS. Mines, Workshops, and any others that may be added, such as lumber mills line, all should only upgrade with time worked, the same as cottages. You can't build a Town immediately, and pillage it down, it has to grow again.
March promotion, its not working on ICE. Is this Working As Designed (WAD) or is it a bug. They will heal on ice if not moving, but move and they lose health.
*Edit* Blitz isn't working for Mech Infantry either. I've attacked a target with a blitz enabled unit, and with 1 move remaining, it can't attack a 2nd time. I can also promote new units to Blitz, so looks as if should be working, but isn't.
Can build the UN mission, when I have built/own the UN building myself. Again WAD? Probably as can lose UN, but shouldn't be able to build UN Mission, unless don't have UN, as only 4 available, takes away 1 spot (should be given with Owning UN.)
