If I put the same ability in all four attack slots they each have their own individual cooldowns. Don't know if this is intentional but it feels like a bug. For example, I added cleave to lmb, 1, 2, and 3, and I can now instantly use cleave 4 times all at once.
Pushed a server fix just now. Also added it to my client fixes to just in general not allow the same ability multiple times, but that will go out later, but for now cooldowns should be per ability instead of per slot like it was previously.
There shouldn't be healing outside of being online, if there is it's a deep seated bug somewhere I'm not directly looking, but when a character saves, it saves with current and max health.
