What do you have set for hitDirectionOverrideEnabled (see documentation)?

There was no wipe with the 1.15 update.
DayZ Staff can not and do not have access to BattlEye global or VAC bans, and can not revoke them in any way possible. You MUST contact the BattlEye (in case of game ban) or STEAM support (in case of VAC bans) about any bans issued on you. If you have a verification from Steam that your account was hacked in this time frame, you can forward that mail exchange to Battleye to prove your innocence.
Closing the topic.
A video would be appreciated indeed. With "locked", do you mean you used a lock pick, or did you just close the door? Do you know if the door was just locked before the infected passed through, or if there might've been a server restart in between?
