OpenMW-CS, Scene view: Extended selection of all Instances with the same Object ID only selects Instances in the same cell(s)
When you use the extended selection of all Instances with the same Object ID, only Instances in the same cell of the formerly selected Instance are selected. This is also true for Instances with the same ID but located in different cells: OpenMW-CS only selects all contemplable Instances in both cells. When you select two Instances with different Object IDs in different cells and choose the above-mentioned option, OpenMW-CS selects Instances for the first one only in the corresponding cell, whereas it selects Instances for the second one in the other cell only.
This issue was tested with the v0.39.0 RC from Ace (Windows). I used an .omwaddon file only depending on Morrowind.esm.
