Hello!
We had a fix recently to address monsters without Deft not being able to activate crystals in the Ancient path and one for monsters not being able to activate "special commands" like the Ancient Bones.
It turns out these issues could still happen under some specific circumstances >.<
Patch 1.3.3 fixes that, this time for good!
02/07/2020 - Version 1.3.3
Bug Fixes:
- Ancient Path: There were still circumstances where monsters without Deft couldn't click the crystals. Fixed!
Balance:
- Bzil Units: Will now gain vicarious AP from monsters (for the respective monster class) for missions AP as well as battles. They were already gaining it from battles.
