Member cM_rand_c::ranqdStep (): The implementation is flawed. This post explains why.
Class daObjFruitTree_c: Bushes with sizes larger than SIZE_SMALL spawn too late when approached from above due to the bounding box not being updated.
Member daPlBase_c::setStatus (int id): The implemententation of this is broken. Presumably this was written before the status bits were split up into multiple bytes, because it only clears the bits in the byte where the selected status bit is and leaves the other status bytes unchanged.
