I've added a printline in the rules xml file before the insertLogical. At
one point shortly before the corruption occurs the following two lines
appear immediately one after another:

inserting FamilyStart for Family 11 at tijdslot Timeslot 5
inserting FamilyStart for Family 11 at tijdslot Timeslot 7

This seems strange, it's as if they're inserted almost at the same time.

FamilyStart implements it as follows:

@Override
public boolean equals(Object other)
{
	if ((this == other))
		return true;
	if (!(other instanceof FamilyStart))
		return false;
	FamilyStart castOther = (FamilyStart) other;
	return new EqualsBuilder().append(this.getFamily(), castOther.getFamily())
		.append(this.getTimeslot(), castOther.getTimeslot()).isEquals();
}

@Override
public int hashCode()
{
	return new
HashCodeBuilder().append(getFamily()).append(getTimeslot()).toHashCode();
}

Similarly,  FamilyEnd:

@Override
public boolean equals(Object other)
{
	if ((this == other))
		return true;
	if (!(other instanceof FamilyEnd))
		return false;
	FamilyEnd castOther = (FamilyEnd) other;
	return new EqualsBuilder().append(this.getFamily(), castOther.getFamily())
		.append(this.getTimeslot(), castOther.getTimeslot()).isEquals();
}

@Override
public int hashCode()
{
	return new
HashCodeBuilder().append(getFamily()).append(getTimeslot()).toHashCode();
}
