1. When building the KT-4, the spider does not explode after being extracted. This can be confusing as if you lower the cage again, or try to take the spider venom, you cannot. The easiest way to work around this bug (for the moment) is to shoot the spider in the cage AFTER it has been extracted
2. When using the KT-4 or Masamune WW, when zombies die, there is a chance they will instead just become invisible but unable to hurt you. This can be fixed by running away, forcing the zombies to despawn and respawn. Recommend NOT using the ww on this map at all unless for the boss or plant fertilizing.
3. You can duplicate the amount of zombies that spawn on a round simply by running from the green water area, to the challenge podium, if the door between areas is locked. (Basically running through spawn to the challenge podium. Basically the long way.)
4. You can't pap the wonder weapons, but you can spend points to upgrade the enchantment on it. (This applies to all maps, including SOE, Der Eisendrach, etc.)

Hope this bug reporting helps! I love this mod and wanna see it flourish more!
