It has been brought to my attention that there has been some confusion regarding energy and the timing for its consumption. And rightly so, I don't think I've done a great job explaining that. And it's been a WIP this whole time. So lets throw down some guidelines
For challenges, I will be making a post with your treemail before I introduce the challenge. 24 hours later (in general) I'll be making the challenge details announcement. Along with the treemail, you will be told the increments you can spend energy in. You have until the challenge details announcement to state how much energy you will be spending. This energy will be deducted at the beginning of the challenge.
The challenge details announcement will include the amount of energy participating in the challenge will cost you. This will be deducted at the end of the challenge.
Any energy or morale gains made during the challenge will not be totaled up until the end of the challenge. This is for my own sanity and for simplicity. So if you are below 50 at the start of the challenge, you will have the disadvantage for the whole challenge. Your energy gains and morale during the challenge will be totaled up before the deduction of the energy from participating in the challenge. If this total exceeds 100, the excess energy is just lost. And as I type this and think about it, I might not have done this completely right, because you should never be at 100 after a challenge. Since this is the case, I will be updating energy totals again tonight, and possibly even looking at the way I'm doing energy stuff. This will push back the immunity challenge details at least 1 day while I look into this. Sorry for the delay.
