As for drone/not drone,what I digged for now:

Toropets weapon storage is an old place. Today it consists of two parts - old USSR surface storage (hangars in the forest) and new one, underground facility. From the latest Maxxar images you could clearly see that only old, forested area was seriously damaged, and new one, with separate underground chambers didn't. There is no problem to blow up surface hangar in a forest with a drone. Looks like that bureaucrat who supervised building a new underground storage and was jailed months before hit, delayed moving stuff from old hangars to underground chambers or just didn't bother about that old stuff. So, something was left in old surface hangars and detonated after a drone strike.

Probably as one of immediate consequences of that hit all other such storages that had to be modernised will be inspected, so may be more trials coming and more bureaucrats will be jailed. :)
