It's possible that due to random generation, there was nowhere the Burial Chamber could spawn that was within all the acceptable parameters (Has to spawn on land, within X of the ziggurat, but not too close to POI Y or Z)
If you disable the missions and resume it, it will show in the console whether or not it could find the POI on the planet. If it couldn't you cannot proceed; at least not unless you go to another starting planet that has a duplicate of the POI.

Same problem on Omicron. Console shows that it can't find it. I guess I'll try another planet.

Hi guys!

Same problem with Ningues: it's exactly the behaviour described by Vermillion.

I've made a full analysis of the problem in the main forum also with screenshots, here:

https://empyriononline.com/threads/reforged-eden-scenario.94773/page-99

In my scenario there is a further complication: the game is unable to find a proper POI not just in all the starting planets but also in the other ones in the system (proves are on the link above).

In my opinion we may even try to identify this thing as a bug of RE: maybe the coordinates x, y, z Vermillion was talking about were set with too strong constraints to be satisfied by the POI generator.

Maybe in that questline we can try to change those constraints.

Please note that this 'bug' is definitely blocking and it seems that as of now we still don't have a fix.

Same problem. Omicron.

I've tried all the planets in the Beta starting system with no luck. Is there any way to work around this bug using the console? Maybe spawn the structure? Or disable the mission, use the console to destroy some POIs, and then re-enable the mission?
