Current state of greater invisibility?

[HaleMary]

Greater invisibility has gone through a lot of bugs, fixes, fixes that were then rebugged, etc. Does anyone know how it's currently working? Specifically:

1) Attack bonus. Being invisible is supposed to grant an attack bonus against enemies without truesight, but this was bugged. Is it working now?

2) Defense bonus. It's supposed to grant concealment, again to enemies without truesight.

3) Mind blank and truesight. Update 1.4 supposedly made mind blank negate truesight. So if you have both invisibility and mind blank theoretically enemies with truesight shouldn't be able to see you, granting you both of the bonuses above. Does this actually work? Has anyone tested it?

Higher level enemies can generally see you if you have Greater Invisibity, although they have to make a Perception check to spot you. My Trickster MC has the reuse Magic Device Improved Mythic Trick, so I can cast Greater Invisibility from my wand without using charges, so my party generally starts the encounters at Threshold (the final encounter area) with everyone buffed with Greater Invisibility.

It has been finally fixed. Greater Invisibility + mind blank works against true seeing now. It does not help against echolocation but most of the enemies do not have it.
