Got an extremely odd bug, in v42 with orgasm in a can and the restart button - It seems like I can break T1 innocence... without breaking T1 innocence.
Save is C1-Bug.
Minimum steps to reproduce: Start battle with OIAC active (should be on by default). Immediately restart battle. Slime, Attack, Surround, Caress, then Pummel or Humiliate.
I'm pretty sure this classifies as an exploit, it lets you farm the +2 EE from breaking a minor T2 multiple times on Day2, giving you a lot of initial EE generation without actually breaking any of the chosen's vulnerabilities.
Edit; Actually, this might be a deeper bug than just in the above scenario, though the above does allow this to be easily tested. From what I can tell, it looks like restarting a battle prevents T1 breaks from "sticking" at all. After restarting a battle, any T1 breaks will still generate EE, but they will still be considered as unbroken by everything else. So you can break the same T1 multiple times, ignore distortion T1 breaks, and essentially farm the +2/+3 EE gained from breaking T1 during battle.
