Re: [Rails-devel] Further 1835 testing

[John D. G. <jd...@di...>]

This save file is a later one from the same game, and shows an amusing
stock-market bug.

At the point of the save, John has three 20% certificates of OL.
If I click to sell some of them, the program offers to let me sell either
one or two 10% certificates, or one or two 20% certs, but not three 20%
certs.  (So apparently the game engine "thinks" I have two 20% and two 10%
certs, but that is not possible -- with 30% still in the IPO, only one 10%
cert has ever been purchased.)

It gets even more interesting if I take the program up on its offer to let
me sell one 10% cert.  When I do this, I am credited with 86M and the share
price falls as if the sale had taken place -- but all holdings stay the
same: I still own 60%.

It gets still weirder if I "Forced Undo" the sale: Undo does nothing, but I
can "sell" another 10%, again gaining the market price of one share and
dropping the price further while giving up nothing.  (The "Game Report"
window does not reflect the Undo so maybe that is a no-op here.)

(A possibly related annoyance I found earlier: If Marcus wants to sell some
of his 15% holding of PR, the interface allows him to sell either his 5%
certificate or his 10% cert, but not both at the same time.  I can sell one
at a time, but this causes the price to fall twice, which is not possible
under the rules of 1835.)
