[1.1] Combat log error "Could not resolve any root"

[Esredar]

My colony was attacked by a pack of manhunter raccoons. This particular raccoon attacked the door for a while then decided to try something else but was killed by a wild cobra. There were dead raccoons everywhere so I wanted to check the combat log. The message looks weird, as if a particular condition was not dealt with in the code.

I strongly suspect it is related to the attack on the door, especially since a door was also involved in this similar bug report: https://ludeon.com/forums/index.php?topic=50442.msg471018#msg471018

Not sure if relevant but this colony was created in 1.0 and was updated to 1.1.
