I had a quick chat with old Antica players and it seems both Venore and Ab'dendriel had daily respawns of yellow roses, both previously mentioned here by other users' answers.
The one in Venore was supposed to be unreachable but a bug would make it possible for players to get it. The table where it would spawn was located north of the city in this room:
In Ab'dendriel the rose would spawn on floor +2. One would need levitate or parcels to reach it. Unfortunately I have no screenshot to exemplify but here's the location:
According to my source the yellow rose was removed 2 or 3 updates after Ab'dendriel implementation, so either version 6.4 or 6.5.
I couldn't find any information on the Fibula spawn, so I can't confirm whether that was an actual thing or not.
