The above suggestions can be worked around by having the LMD restart or just replacing LMDs. It could slow things down but won't get rid of the issue like this update does.
Siege morale will be removed in Update 2.220 (should be on 19th August) in all morale CQ worlds (except CQs on Ghost towns).
I want to get an idea of people's opinions on this update. Also would be nice to hear comments on it as well.
