I was running the Dawn Circuit on “Master” difficulty and finished my latest run. I had 11 energy left.
I then decided to switch to “Ultimate” for my next run, but to my surprise all of the energy was gone and reset to 4/4. When running on master all morning the energy persisted through each run.
I can retest this and get a video to verify if you need it, but I am sure the account logs will show it.
I will leave this here as informational instead of a bug report.
It appears that each difficulty level stores energy separately from others.
I was playing difficulty 4, had 11 energy left over when I completed the adventure.
Switched to difficulty 5 and the energy started at 4/4. After this adventure was complete I switched back to difficulty 4 and had 15/4 energy. So all of the energy is intact, just in their own adventure.
Maybe a bug… not sure, but at least there was no loss of gems.
I can confirm this as I posted about it on our Playstation Kingdom thread this morning. You don’t lose your energy, it’s simply stored for each difficulty level independently.
