Big thanks, I will try it out 
Btw.: Do you mean replacing every call to “wait for ongoing actions” with this solution? Or just at this particular point?
To the second one: Have you set up “Move_Attack” and “Heal” to not end the units turns? Or the other way around - are your (and AI) units able to use more than one ability in one turn (including movement?) Yes latest version.
But maybe those problems were tight together, so that it is fixed by your first solution , I will report back after further testing, thank again
