Bug present at least in v1.8.4
Context :
p23 of the rules book : If the CGR is formed and no player holds more than 1 CGR share, the first player who received a CGR share is designed as president of the company and receive the president's certificate (so he virtually receives one more share than he actually holds). Then, this player is forced to buy the complementary share at his next stock market.
Bug :
This rule is implemented in "StockRound_1856.java", line 155 and subsequents, but there is a bug in lines 182 and 185 that treat a share of CGR as 1% of the total value, leading to a "$0" cost by share. A message appears to warn the player he is forced to buy a share for $0 ! It might be good news for him but this seems to prevent the player to buy the share and this blocks the game.
Solution :
Replacing the wrong "1" by "10" in cited lines correct the bug. (tested)
But this does not take into account the variable 10% or 5% share property of CGR certificates !
