Spiritus Astrum [P0-B11]: p1499: Towards Early Access

The testing of the third campaign is continuing to go well.

I have run into a few minor bugs, which were fixed, and I also made some small improvements to the campaign as well.

There was one more serious bug that I found with the AI navigation system, but this was also fixed. It turned out to be a relatively simple fix in the end, but due to the complexity of the AI navigation system, it took a while to find it.

I am nearing the end of this round of testing, but there are several improvements that I need to make, as well as some bugs left to fix. Once these issues are solved, I will do another round of testing.

I also have more art assets to add to the campaign, etc.
