So I have been playing 1.1 further, I have discovered three additional bugs beside the concrete wall bug.

1. Some rooms are clipping into each other(That bug however has been there forever and is probably hard to fix)
2. In SCP-106's containment chamber, an white square is appearing, where normally, the SCP-106 containment label should be in(The same bug is with the Radical Larry picture in the head office.)
3. Sometimes sound files(Especially when characters are talking) end abruptly even when they normally are not finished yet.(For example, the officer in the SCP-1123 event tells the player to follow him. While he is saying that, the sound file stops playing even when normally he hasn't finished talking.
