[V18.5 - Ground Combat] Reproducible hidden movement hang due to stun grenades

Load the save game at http://173.212.225.56/Autosave2.sav

Move Hunter Scout Car and Xenonaut to these positions:

Thow three stun grenades at the alien.

Hit "End Turn".

Listen for alien shriek during Hidden Movement screen. If it doesn't pass out, re-load and start over.

Hit "End Turn" again.

The Hidden Movement screen will come up and never go away.

Thank you, also for the save file.

I had the same thing happen with a stun rocket, so I believe the problem is related to stunning certain creatures in certain situations.
