I didn't know what was causing the thing I have discovered in game but when I found this task and tried to reproduce it, it seems to be the match for the thing that was happening to me. I think I did used stored strike there, but I don't remember for sure if that was the case.
What I am saying here is, that I am not entirely sure that the stored strike is behind it but it seems to fit pretty much.

Well I am quite sure that is the evolved version of T831: Cantermore library building collision issue. First no collisions than entire building goes poof, RIP library xD. The mentioned task created by me can be now basically closed, probably as invalid since this task refers to the same object, updates the problem and reported in the current version.

Reproduced this issue as well.

Game client version:
Build : v 0.1.2

Created a possible duplicate of this task: T653: Arrow keys controls assigment . I apologize, its hard to look if someone hasn't already reported something with all those tasks and unnecesary duplicates.

Same here:
