We were playing last part of oryx raid tonight and when oryx had almost nothing of life, we thought the next round we would kill it... Guess what? We fired all kind of stuff as usual and oryx kept same level of life. We went to next round and the same happened! The third time we continue firing with all wepaons and nothing until all of us died at same time. This is really frustrating. We play to grt fun but also to complete the challenges and raids. And these kind of bugs does not help anybody.
