So me and my friend decided to make a base. After 2 days of playing we finished main gate.
Combination Lock did not open after entering proper code.
We had to destroy the gate and we made it again, and the same thing happened, it happens when server is about to restart, but not every time. My friend went to check our base in the morning, and he checked the gate, it was working, he was able to open it, he did it twice, closed it with combination lock and left server.
After time i joined the server, entered the code, and nothing.

It was on experimental version of the game.
