After acquiring 2 punched cards and using one of them to open the bunker entrance on 1.19 Livonia experimental, I had found that the second set of doors (not the big bunker doors but regular ones with a key hole in them) leading to the main interior part of the bunker had been closed by another player with a lockpick. It was impossible to shoot/punch the doors open with guns and melee weapons. Pressing F to interact with the doors would just produce a closed door sound. It seems as though the only way to open it is to find a lockipick, nothing else is working. Since I had not found a lockpick during that session, I am stuck in the bunker with no means of escaping, unless someone else opens the main door from outside or wait for the server restart with hopes of doors becoming unlocked afterwards.
