We did update and reseeded our server some days ago. Even we set regen poi's to true in the gameoptions.yaml, there have been no POI's or asteroids regen/respawn after 4 days... So no idea what going on ..
Did you leave at least 1 block of the POI? Did you leave at least a little of the rock of the space asteroids? Sorry, but I am no help after that.
Yeah, there was plenty of blocks left. But nothing respawn of POI's asteroids etc. Not so bad if you the first couple players that start on the server, but the next ones won't really find any resources at all, which kinda suck.
You need to change the gameoptions in either EAH, or under the save game folder, for an existing save. If you did this and it still isn't working and you're using a rented host, you will need to contact the host company.
POI regen was set to True in the gameoptions.yaml file. so that wasn't it... Eventually all kinda weird stuff started to happen on the seed. So we did reseed and restarted the server, and it worked. Gremlins in the machinery? idk..
