Version: Build 82066 expansion, win64

If you walk till the edge of a pipe, it is still possible to place a underground pipe under your feet then you can get stuck inside the underground. I tested for many directions and it works in every direction. I guess that is propably because from what I see underground pipes have no collision checks.

Thanks for the report. This is not a bug.

In 2.0.7 they were made walkable:

I am sorry, I didn't confirm the reason of why you can get stuck.

When you place a underground/normal pipe then the collision box of the pipes next to it changes so there is no gap between pipes. Because you can place a underground pipe under your feet you can expand collsion box of a pipe into players collision box, so you get stuck.

The issue doesn't exist with normal pipes, as player has too big collision box so you can't place a pipe next to you.
(as a side note, if you walk faster then you can walk out of it)
