The game was created on 4/11. It's now 9/11. Both direct and auto are at 3 days, but Summer has not been force-joined, nor do I have the option to do so. She isn't on vacation, either.

Am I missing something obvious?

you have to w8 she join.

I can only think of two possibilities that explain this. Either Summer was on a vacation and it just ended, or it's a bug. The auto-booter / auto-force-joiner can take several hours to act after someone's vacation ends.

If they still aren't force-joined by tomorrow, please report it at http://warlight.net/ReportBug

I didn't notice Summer being on vacation, but it is entirely possible, and indeed the most plausible solution.

I'll chuck a bug report in if it doesn't resolve itself overnight.
