Broken flag carrier trails in CTF
The flag carrier trails in CTF are buggy. Sometimes they go across the whole map (probably has to do with the enemy FC becoming visible again after they disappeared behind a wall?). It has been like this for years (Since they were added I guess), but I wasn't able to reliably reproduce it. It happens pretty much randomly and not very often. You can guess where the enemy FC is when the bug occurs, which kind of sucks in CTF.
However, I just noticed that it does happen with warp zones as well. Here's a video demonstrating the issue: https://s.nxs.re/flagtrails.mp4 . The rooms are separated by warp zones.
