After defending a base from a Pandoran attack, killing all the attackers without them setting a foot (or claw) inside the base, the base was still ransacked and every building destroyed.
Occured to me as well. This is problematic, it takes a LOT to repair a fully-built base.
One strange note, when starting the defense, the ‘Defend Vital Structures’ was at 47% right off the bat. No further damage happened to any base structures during the defense.
Same problem here, main base structures at 1% after succesfull defense, they did not even moved a step into the base. This completely ruins the whole game cause I’ve to spend all resource to reapair base.
If this wasn’t fixed in the hotfix, try loading the autosave if this happens.
Experienced a similar issue on 1.7.1 Necromonicon WSA on Game Pass without any DLC.
I replayed a base defense three times from manual & auto saves and buildings would finish either at 1% or partial% after killing all enemies without losing base structures.
On third reload, I found the mid-game saves started with buildings already damaged.
On fourth reload, I manually and loaded that save before doing any actions. I checked the structures to make sure they were undamaged in the reload and was able to complete the base defense.
