Improper Lighting (again)
When you place lava behind glass, the light is improper. This is only fixed after another light source is updated. In some pictures I could not do it again. Sorry
. Also while I was updating the post, i found 1 more lighting issue. Here, 1 out 4 blocks is lit for some reason (There wasn't any light source in the area (My brightness was set to full BTW))
