A few bugs with Gothic 2/vanillla/opengothic V. 1.0.3756

[ghost]

Generally speaking, the game is working well and is very stable.
I went through (vanilla) as a paladine without big issues.
Now trying as a magician.
In both cases, I could find a few bugs.

1. Something is wrong with the long range weapons (bows, crossbows). Using stronger weapons has a strange impact:
   you still need about the same amount of arrows/bolts to fight against an enemy. Just the previous, lighter weapon requests much more amunitions. Now, as a magician circle 4/dexterity 72/Dragons hunting, I still need around 50 bolts to kill an Orc Elite with a heavy crossbow and 30 for a simple orc warrior.
2. Loading runes (e.g. large fireball) is not working.
3. ice golems are not throwing "ice rays". You can see them balancing their arms, but without further effects.
