[1888] A difference between 18xx site and the rule book of 1888

[cincinno]

When I played 1888 on table with using 18xx site to check our operation if right, I found a difference between 18xx site and the board.

The ability of private company——Forbidden City is wrong. On the site it is:

A player owning this private company may exchange it into an IPO share of a company with a token in Beijing (at the time of exchange). If sold to a company this ability is lost.

And on the rule book it is:

During a stock round, a player owning this private company may close it to take one share in the IPO or the bank pool of a share company with a token in Beijing (at that time). This counts as a buy action and the player cannot sell anything the turn they're doing it. If the private is sold to a share company, this ability is lost.

The difference is that on the site the player can only exchange the company into an IPO share, and on the board the player can exchange the company into both the IPO share or the bank pool share.

I wander that if 1888 on the site can align to the rule book.
