playing moon base 7.13.2017 i happened to see a yellow and blue player triangle with no character underneath, thought it might be an assassin, but when it killed some1 i say it was a gunner, so i hunted this down and the smaller pic with the yellow triangle with nothing under is what i saw, not sure if this is a hacking thing or an optical bug??? http://prnt.scfvggug yellow triagle is on the left side of the capture point area.
Link not working, bad extension.
It’s visual bug 
Also might be ur graphics card, but most likely they got randomly bugged.
Also don’t create topics for every post, use this one instead
https://forum.id.net/t/report-bugs/2061/386
Or any older one that is still active and used for reporting players, off-topic talks or u can constact Ankit/me if u find any issues.
Other thing is how for bugs/hacks video is needed, like this we can only guess issue that u faced.
