Thank you for turning in these issues! I checked and it really is like that for the orc in version 1.0, which is quite weird as for example, passive healing works for the human...
I could not replicate the materia quest issue you mentioned, though, but will look into it regardless.
These issues will be fixed in the next version, which will (hopefully) be done soon.
If you experience any further bugs, I will be very pleased if you tell me about them.
Again, thanks for reporting these!
EDIT:
Just found the issue which prevented you from healing! If you hadn't mentioned it it may have gone unnoticed as it was a 0, where 1 should have been written. Thank you!
