I've come a crossed a bug when the sentinel has the second wave option. When the raider hits it with a plasma bow, the bolt just bounces off as seen in the video below.
Thank you for taking the time to report this issue, we are forwarding this to the team for their review.
just another example
not a bug. thats a function of the light bow. it's shots can bounce off walls.
not positive on exactly how it works but i've seen it used to shoot guards around corners off glass.
There are times it will stick with the bow and times that it will not. All on the Sentinel with second wave. It's hit or miss when it happens.
from what i've discovered while testing. any naturally occuring bedrock will cause it to stick, player placed block or 2nd wave will cause bounce.
