If you are a map-hole inspector, we have new technology that will aid the Dev's in patching up holes!
At this time the technology is PC only using the native screenshot function (F6). Steam overlay capture will not work.
So, how can you get involved?
1) When you encounter Map-Holes/Level bugs, press "F6".
2) The screenshot (saved by default in Pictures\Warframe) now has stored meta-data to point our team to the exact tile involved in the bug.
3) Upload the screenshot via attachment
