[Rails-devel] Bug Report 1830 Rails1.7.2

[Mike B. <com...@ip...>]

While playing a game of 1830 (simple Option) recently, I noticed a pair of
subtle bugs in the game system. Log files for these bugs are not available
but saved games are, and I have verified that the bugs are reproducible
using the specific techniques described below.

Bug #1: Problem ending company Op round when president has been forced to
sell shares.

Details: The B&O president has just been forced to sell shares in order to
raise the capital for a diesel. Play then moves to the newly-launched C&O,
but the game freezes. C&O never gets to lay track, the map window (top left)
reads "lay token" and "no token" and both choices are greyed out, as are the
buttons at the bottom of the map window ("Done", "undo", "redo"). However,
as soon as "save game" is performed, the problem clears itself.

To reproduce this bug:

1. load 1830_20120415_0220_M4.rails.
2. In the game report, locate and click on the entry that reads "B&O does
not pay a dividend", then "play from here."
3. In the map window, click on "buy train". Note the relative order of L&N
and C&O shares.
4. Sell 2 shares of PRR, 1 share of NYC, and (critical) 1 share of L&N. Note
that the relative order of L&N and C&O shares have changed because of the
sale of shares.
5. Click "done".

Bug #2: Incorrect display of company names when returning to an earlier
action and clicking "play from here".

Details: shortly thereafter in the same game, the L&O took its op round.
Despite the "unlimited tiles option being turned on, the game would not
permit a standard yellow city tile (57) to be placed at location H4, the
L&O's home base. This appears to be due to an incomplete processing of past
actions in the "play from here" function, specifically stock movement
resulting from the forced sale of shares.

To reproduce this bug:

1. load 1830_20120415_0224_M2.rails
2. In the game report, locate and click on "M2 sells 1 10% certificate of
NYC to pool for $50", then "play from here".
3. In the Map window, note that the relative order of L&N and C&O shares is
the same as before the B&O president sold a share of the L&N even though the
game report shows this event as having occurred.
4. In the Map Window, click "done".
5. Game will not permit L&N to lay a tile in it's home base. The game is
highlighting valid tile lays for the C&O (which SHOULD operate now) and will
permit either of those tiles to be layed.
6. If you lay a tile, click "no token", and buy a diesel, it is the C&O who
gains the train. Click "done".
7. Play then moves to the C&O according to the (incorrect) map window
display, and all actions appropriate to the L&N's turn (tile lay at H4,
purchase of a diesel etc).
