If players start upgrading a building or troop before an update is announced, would it be possible to prorate their upgrade and/or cut their upgrade time remaining?
The tesla upgrade removed 2 days from the upgrade time.
The new level 7 archer reduced the cost of the level 6 upgrade from 7.5 million elixir and 14 days to 6 million and 10 days. This is sort of unfair for players who do the upgrade then get ripped off by reduced prices and upgrade times.
