Water services not storing
Don't know if this is fully a bug or a ridiculous design flaw (hard to tell these days) but you can store services acquired in the Maxis shop or awarded from event tracks, etc...
... except water services. I've now lost 2 water buildings using them on blueprint challenges thinking the 1st one was a one off glitch or a misunderstanding on my part.
If it's a bug, I want the water items back that I spent seasonal currency on.
Another services bug is emergency services saying they're not covered when they were and no buildings have been upgraded. But if I move a residential out and back in again it says covered. Wasted a lot of simoleons until I figured this bug.
All the options for Water are now permanent options in the game, rather than limited time buildings. None of them are storable any more as a result.
