Can't believe it took me this long to get back to this. Thanks for your replies.
No I didn't delete any boost buildings & the only coin boost was from a "Classical Garden Statues". I wish I had some exact #s for you, but since I hadn't expected them to all go down, I never thought to note what they were. I just have this sense, after having had most housing types up to that point for a long enough time, that they all had been higher. The values just don't look "right". And I mean the base values in the construction menu, not just in my cities (B, Y, & Z). I know Roof Tile Houses were 25/15 minutes with enthusiasm but without motivation (so 100/hr hence why I kept them) so I think they were 21 base and now they're 15. Also, the Villa was 400 something per collection with enthusiasm & motivation (I was stoked collecting from those) then they dropped to 200 something & equal to the Longhouse. I just don't get it. I never got a notice there was a glitch with my account & had been getting too much. I was hoping others had noticed this too or there was a game notice I had missed explaining an overall change. Current base values I see are 15/15" Roof Tile, 110/4hr Cottage, 100/hr Villa & Longhouse, 80/4hr Chalet, 32/hr Thatched, 11/15" Stilt, 6/5" Hut. The RT Houses have now lost their "woo hoo" factor & I've replaced them with the Cottages.
