Traps Despawning

[Vogelens]

Today in a dungeon, I discovered that any traps my rogue set despawned immediatly. Another player said he had the same issue before, with a trap user.

If it helps, the traps were a Minor Fire Trap and a Minor Electrical Trap that I used.

I can confirm that this is an issue, although my experiences are limited solely to underground dungeons and locations in general. The traps used were both minor, Tangle and Holy ones. Maybe it has something to do with limited space?
