Fight.cs, doCleanup(), List modified in enumeration

Lines 232-241. There are list modifications in enumerations here:

            foreach(Entity e in liberals)
            {
                if (e != null && !e.getComponent<Body>().Alive)
                    liberals[liberals.IndexOf(e)] = null;
            }
            foreach(Entity e in conservatives)
            {
                if (e != null && !e.getComponent<Body>().Alive)
                    conservatives[conservatives.IndexOf(e)] = null;
            }

It crashes for me when someone dies:

InvalidOperationException: Collection was modified; enumeration operation may not execute.
System.ThrowHelper.ThrowInvalidOperationException (System.ExceptionResource resource) (at :0)
System.Collections.Generic.List1+Enumerator[T].MoveNextRare () (at <c8d0d7b9135640958bff528a1e374758>:0) System.Collections.Generic.List1+Enumerator[T].MoveNext () (at :0)
LCS.Engine.Scenes.Fight.doCleanup (System.Collections.Generic.List1[T] liberals, System.Collections.Generic.List1[T] conservatives) (at Assets/Scripts/Engine/Scenes/Fight.cs:232)

It's more correct to use an enumeration of indexes or to store indices in a list, e.g.:

            foreach(Entity e in liberals)
                if (e != null && !e.getComponent<Body>().Alive)
                    indicesToClear.Add(liberals.IndexOf(e));
            foreach (int index in indicesToClear)
                liberals[index] = null;
            ...
