It is just a visual bug with no direct effect on gameplay mechanics. The tether between two people, which are spawned during the goalmechanic in the boss fight "titan extreme" can stay forever. If one of the tethered player dies(because of the landslide for example) before the goals/traps are created on them. This can be difficult for new players to differ between the real mechanic and just the bug.
[Never seen this bug before the patch, therefor I assume it has to be because of the newly added feature, that dead people are moved as spectators back on the platform and so the link is still visible to the very middle of the arena, where probably the spectatorcamera is.]
If same person(this case healer) gets the tether again, the tethers overwrite and it will be normal again.
If not, there are two tethers visible in the next goal mechanic.
I saw the bug now atleast 3 times, I am just not sure how fast one of the tethered player has to die in order that it stays permanently.
