Feel free to mention things like this i myself like to be as perfect with everything i do as much as i can and are very judgemental on my own stuff ,i have seen this and it could be a result of the build values or more likely a straight trace to the target instead of pathfinding through every polygon ,could also be with filter costs ,wil check this out and perhaps ask mikko and the other guys for some help if i cant find it myself . Thanks man ,i worked realy hard on this up to now even though it seems basic to me yet ,not alot of sleep so there could be perhaps more little problems along the way only usage and time wil reveal
