A little patch to correct the first bugs that you have reported. Should be savedgame compatible, but you would better start a new game to see the changes make effect. You only have to unzip into your LBCE installation folder and overwrite.
-Fixed bug at Jayek scene that made the defenders not appear (or training peasants)
-Crossbows, 2 handed swords and cavalry lances will no more appear at tourneys. You will instead have wooden staffs and throwing daggers.
-Tourney horses nerfed. They now die more easily.
-Tourney swords nerfed. They now swing slower.
-Fixed invisible heads at Calradic tourneys bug.
-Fixed bug at spanish texts in Luka's dialog.
-Other minor changes at scenes
