Online official Bug PvE EU: [Please enter your server region]
I was upgrading my set altar to the highest tier. I was excitedly watching the little white bar go up slowly then ultimately despawn the whole thing and drop all the loot it contained. So now im here with no altar, wasted resourses and a little bit pissed, looking for help.
I know in the past Set alters would jump forward a foundation so if you had it with the front up against a wall it might’ve despawned because it didn’t have room to place.
Also sometimes a problem if you set it (no pun intended) to upgrade and went out of render range, so that could be it.
Or if you didn’t have it on foundations, that can cause problems too.
The only thought I had is that the altar had little room to work with on upgrade. Which is part of your first thought, but the altar doesn’t/shouldn’t jump forward any more.
This is a long-standing bug that people have been reporting since release. Unfortunately, it seems be random and difficult for them to reproduce. Because you’re playing on official, and Funcom has a “hands off” policy towards their servers, you’re out of luck, sorry to say.
