When doing weekly keyfarm on 25th May 2019 as lvl 21 human engineer, trying to use grenades to kill the bandits in the building in Hospital in Jeopardy-story instance failed. For whatever reason the grenades didn't explode in most parts of the building. Since it was an obvious non-critical bug, Kitty recorded it on a video for later inspection (and she totally forgot about it for 3 weeks).
It's Kitty. The young lady who streams and records videos playing various (non-)metabuilds. Raid/fractal videos at youtube.com/LadyKitty, Kittymarks test results at youtube.com/Kittymarks and tinyurl.com/Kittymarks and streams at twitch.tv/ladykittygw2 .
