[2019] Units randomly will not attack the closet infected after using the attack function

Hi

I have been cheking and testing and i cannot be able to reproduce. I have tried with previously damaged zombies in front of the troops with non-damaged one coming from the back. I have also changed from Highest to Closet....

All has worked fine.

Any suggestions?

Thanks.
