1-The first bug happened, when i managed to notice them, because the event that Shin Godzilla died fired before he loaded his units (a condition to trigger the event). To prevent it, i've added more conditions to trigger, such as not being AI, Shin having to complete many focus and a set flag opposed to it as the event that frees him triggers. I really don't know how this could be happening, but i'll take a look right now.
2-Shin and all the Focus Trees will be reworked and expanded for next updates. I've stick to the small Focus Trees as this version is a test run to see how people would like to play or not. But as a matter of example, with the Godzilla tree having 24 Focus as of right now, the next one has 63 so far, as i'm not done yet.
3-This probably has to do with reliability, that made little attrition kill all of them and they simply deleted themselves. I've forgot to look onto them before posting this version, but i'll fix this issue.

Thanks for the report, hope you're enjoying despite the bugs...

I am really enjoying it, so keep up the work!
