Activation groups reset when droods eva

This was my recreation of a bug that Slaviguy expereinced.
Craft has a primary commandchip, a solar panel and landing gear and two drood seats(image 1), I activate all AGs, eva the first drood (image 2), nothing happens.
But when I go and eva the second drood, the activation groups are reset to default (image 3) aka the solar panels fold up and the landing gear remains open
Accodring to Slaviguy this has been a long time bug from before the current and previous beta
