I just used my Trellith ability on a planet and closed it out. I went to check the artifact page and saw my artifact production hadn't gone up. I went back to the planet, looked at the updated resources, went back to the artifact page and now the amount is updated.

This is a design bug from the beginning of the game and it is complained about on and off throughout the years.

If you don't use time vortexes and let your planets mature naturally, you don't get the updated resources until you look at the planet.

If you use terraformers/optimizer/etc and don't look at the planet, you don't get the updated resources.

If a planet is blockaded and you kill the blockade, the reduction in resources doesn't go away until you look at the planet again.

There are probably other places this is going on in the game that I am not aware of but its an issue, a long standing one, please fix it.

I do believe this actually only last until you next get resources, so less than an hour.

Not sure about all the other situations ODrag mentioned, but I do recall Dan mentioning he fixed the planet development issue a long time ago.

You get this issue not just with the Treilth ability also when building planets if you put warp gate down for example it wont show in your resource production until you check the resources page.

If you just close the artifact page with the x in the top it is fine, but if you close it by clicking out entirely it is like a NPC not coming off the bt when disabled.

I confirmed that at least for an optimizer that does seem to do it.

That said, it is still an issue that should be fixed.
