WTF glitch lol

I just experienced this super weird glitch with Sentinel.

I killed this guy's Sentinel by chipping him with Wesker's horizontal gunshot and Trish's Low Voltage assist. But Sentinel flew back like it got wall bounced or something, and when it hit the wall, it disappeared. When the next guy came in, Sentinel's body came out of the floor and did it's normal animation when it's killed on the ground lol.
