It's hard to pinpoint this issue, but based on the fact that this codebase is brand new and I can't see anything that would directly cause, this, it seems to be an issue with too many things happening at once. (powerflowers is where I'm seeing this)

Fixed in 99cec7c, 1.0.2 via the exact method I mentioned above.

What I'm going to try later on today is syncing all power flowers into a central collection, the batch sending the changes off to ProjectE

This will add at least a tick worth of delay to powerflower gains, but that's better than crashes, isn't it?
