Summary: Effect Accounting Occasionally Wrong

Initial Comment:
On the turn after a building is built, or (I think) a special appears or tech is discovered, the list of effects that alter a meter in the UI will be incorrect.  The incorrectness is the appearance of an "unknown" factor in the list.

This unknown is calculated as the difference between the meter value that the server sends, and the value that the player's client calculates.  These are not necessarily the same, as there may be factors altering meters that the player doesn't know about, but should be able to see the net effect of (as one can tell how much food or research a planet produced, even if one can't tell why the amounts expected weren't accurate).

On the turn after a change, the meter values the server sends are the amounts that actually occured on the previous turn.  This excludes any buildings or techs completed that turn.  The player's client calculates the expected meter values on the next turn, however, so that the effects changes due to focus settings or other orders can be evaluated.  These do take into account new buildings or techs, leading to a discrepancy.

The expected value for the player's next turn, and the true amount from the server for the previous turn are compared, and the difference is the unknown factor listed to the player, leading to the unnecessary discrepancy in the case described.

You researched the tech called "Test Tech" which adds these specials. 
This is expected behaviour.  Read tech descriptions before researching
them.

Also, please don't post comments unrelated to the bug you're commenting
on.

Just installed and played with v0.3. 

Researched all 1rp, 1pp items with 12 RP's available.  Do-able in
3-turns.
After a research complete, changed to production of Industrial Center and
Atomic Theory Prover.
After completion, my 'home' planet gained 'specials': slow rotation, tidal
lock.
The effect caused a loss of  1/2 population (30pp droped to 15) and have a
constant drop 
from there down to zero pp,  ultimately ending the game.
