renderregion problem S.O.S.

[Stahlwolle]

Hey guys!

got a problem, maybe someone here knows the solution:

i start a render and everything renders as usual, but if i use the region tool during render and define a region where it should focus on the render it resets all samples in the selected region and starts from 1....
i think this is not the normal behaviour.. could swear i used this before and it did not reset the render within the renderregion. i would expect it just adds there the further samples...

hope someone knows why octane is doing this and how to avoid this!

edit: happens only if i use coherent ratio in the renderkernel settings. is this normal?
