I believe this is different than the below-referenced topic but wanted to note that I was aware of the similarities just so this didn’t get overlooked.
I had a raid that took almost 10 months from the time of Raiders sighted, to the raider report. I defeated them around Oct/Nov in one year but the report didn’t come out until early the next year. I did save and exit before the report came out. After loading the report came out and the only info it included were how many raiders there were, it didn’t have raider deaths/villager deaths/ or buildings destroyed, all of which should have had a value. They didn’t get any plunder, so that is correct
