Panner gets bigger over time ?

Well the problem was that this actually happens with the water mesh, all the levels in my game are played at same location in 1 map, the rest of actors and characters are spawned and destroyed each level, it didn’t occur to me to do the same with the water mesh, just spawn and destroy it each level, so this way the effect of panner getting bigger over time won’t be noticed. However the problem is still there…
