Version 1.0.04 (Solar Observation Description):
- (Base Game & DLC) Improved the description of the "Conduct Solar Observations" challenge.

Version1.0.03 (Loss Victory Fix):
- (Base Game & DLC) - When switching to Celestium, the loss and victory state of the game is cleared.

You know what, I started and loaded a couple time since then and also did not have a save file. If I run into it again I'll get that for ya.

@SnickeringSnaussages I've just searched through Celestium and OrcsPlus and cannot find any error where it reports that it could not find either lunar or solar observatories, using a wide variety of wordings. It's possible that I have missed it, but it would be a lot easier to find with the exact wording.

The game records a log of the current time the application was launched, and the previous time. These files can be found at:
%AppData%\..\LocalLow\FallenOakGames\ShadowsOfForbiddenGods

They are called `player.log` and `player-prev.log` respectively.
If you are able to find the error in the log and paste it and a few lines above and below it that would be extremely helpful.

Hey I got an error playing an orcs game where it was like "cant find solar cant find lunar" and I think maybe it's cause they hadn't spawned that map

Celestium Version 1.0.02 (Lava Pathfinding Fixes):
- (Base Game & DLC) Fixed maths error in the lava avoidance pathfinding delegate that caused units to erronously believe they were guarenteed to die if they tried to get anywhere.
- (Base Game & DLC) Fixed that the lava avoidance pathfinding delegate was being applied to player controlled units, even though they are imune to the effects of the lava.
- (Base Game & DLC) Restructured the lava avoidance pathfinding delegate to improve performance.

@=(FGR)=Sentinel I have fixed the pathing constraint effecting player agents. That was an error on my part. The update will go live momentarily.

As for the Heroes not being able to move, this is a result of a maths error in the calculations for death by travelling through lava. This has now been fixed, and thus should no longer erroneously be telling unit's that they will die if they attempt to path anywhere.

Just a head's up that, from the one time I played through to becoming Celestium, their victory seems highly trivialized for for two reasons:
1. Any units on locations Celestium has expanded to take one point of damage per turn
2. Any non-CO units that end their turn on a location Celestium has expanded to appear to lose the ability to move at all. This also happens to include Celestium's generic agent.
The end result of both these things is simple. Mages sealing Celestium become a complete nonissue if they have to travel through at least one Celestium-occupied region to reach the heart of the star since they get permanently stuck in place and die, meaning they can never seal you. The Chosen One also becomes highly trivialized because they'll frequently try to put up an arcane fortress before they start to fulfill the prophecy, meaning they typically die before they get to the actual sealing step. I'm not sure if this has been mentioned or fixed yet, though.

Version 1.0.01 (Typoes)
- Fixed all typos in Celestium Victory Messages.
- - Thank you to callmesalticidae on the Discord for the proofreading and corrections.

@thatotherdavidguy To switch to Celestium your game must have spawned the Solar and Lunar Observatory wonder pair. If you are starting a new game and want them to definitely appear, you can set their spawn priority to 3 in the mod options.

The information you need is in the description texts for the challenges that are at the observatory wonders.
I didn't include a guide on the mod page, as I wanted people to be able to discover it for themselves. Considering there are two locations, with a total of five new challenges added through the wonders, you would have to check at most 7 tool-tips to figure it out for yourself.

If you don't, here there be spoilers:

You need to charge the Solar Observatory by enshadowing it or the lunar observatory, and waiting. You can view the charge level on the solar observatory subsettlement.
Next, you use Prophecy Starfall from the Solar Observatory, it doesn't matter where. It will leave behind a Star Metal property at the location it strikes.
Send an agent there and gather it using the challenge.Once gathered bring it back to the Solar Observatory, and they, the agent carrying the star metal, will be able to use Prophecy Sunfall, which immediately switches god after completion.

Can you clarify what the condition is to get the new god?
