* Alien nests and some other stuf can be hit again. (#80418)
## About The Pull Request
Another small issue fixed. Thanks Melbert for telling us what's wrong
with it.
EDIT: other objects were rendered unhittable by that flags refactor PR.
## Why It's Good For The Game
Fixes#80311. I made the xmas tree indestructible because the comment to
the `NO_DECONSTRUCTION` flag didn't make a load of sense since that
doesn't stop it from getting destroyed anyway.
## Changelog
🆑 MrMelbert, Ghommie
fix: Alien nests, and some other stuff, can be physically attacked
again.
balance: x-mas trees (the ones with presents), are indestructibles.
Truly protected by a yuletide spirit.
