So I joined a sever to play.. it was in haunt map where I encountered this bug. Some walls did not collide with the character as a result I can move through some walls. Although if I stayed inside for long, I die automatically.
I think this bug has been fixed in the webGL version one but it is still there in the unity version. Earlier also I encountered this bug in base map.
Here is a video that I made of the glitch.
