Desecrated Ground on an in-zone transition

Was running an Arena map, started a Catarina mission: bring Bone Rhoa to the sculpture. Debug number: 1.124.620.152. Character: Drowner.

I picked up four Bone Rhoa in an arena, and hopped down to the statues, where Catarina spawned. One of the Rhoa placed Desecrated Ground on me while I was transitioning between areas, and the debuff remained active until I returned to the arena and walked out of the Desecrated Ground.

Didn't actually realise it was the debuff being stuck until after I completed the mission (I thought they were just placing more Desecrated Ground all over, didn't pay too much attention), so reproducing is a bit of a crapshoot... Doesn't seem to happen with Shocked or Burning Ground either (map mod/hellions respectively).
