Brief Description: You can change what is inside your portal. (I put lava into the portal and it made obsidian. Then I mined out the obsidian on the outside and could freely place whatever I wanted. Also placing water back in or putting lava in makes the portal work again.) Also the corners of the portals aren't protected with the [Stargate], but I'm not sure if they're supposed to be.

Instructions: Go up to a portal with a few buckets of lava right click and it makes obsidian.

How many times did you recreate this bug?: 6 (There's only 6 blocks in a portals)

Result: Obsidian in the portal

Expected Result: [Stargate] Permission Denied

Evidence: N/A
