While playing this game, it froze waiting for the Swedes to take their turn -- or at least it took more than 15 minutes to finish the turn. The game was *minimally* responsive during that time -- I could get the menus to work, etc. I tried \"reconnect\" and all that accomplished was to freeze the menu bar for about 10 minutes. When the menu bar became responsive, I saved the game.
When I reload this game, the Swedes take about three minutes to get through, but does *not* freeze.
Update: I tried to upload the game, but it was rejected by sourceforge as over 256K. The file is 785K.
See this forum https://sourceforge.net/projects/freecol/forums/forum/141201/topic/3513584 for instructions on uploading a split file. Or alternately, just use a public webspace provider (dropbox is a prominent one) and post a pointer here.
This report is unlikely to make progress without the saved game.
Setting to pending, no progress on reproduction.
