Can not place items in basement on ice lake

I figured a visual would help, on an ice lake, you are unable to place items inside the basement that it builds, nothing is obstructing and it looks fine to me, not sure why I cant.

I also have a follow-up question, according to the documentation
 

Destroy Basement Cell When Surface Foundation is Destroyed

true

If true, then when a surface foundation is destroyed, the corresponding basement cell (if it exists) will be destroyed as well.

If false, then when a surface foundation is destroyed, the corresponding basement cell will NOT be destroyed. The only way that basement cells get destroyed is if all entrances connected to that cell are destroyed. When set to false, this makes basements a lot more powerful, as you can do things like have a small base on the surface and a massive one underground or connect two distance bases via a basement tunnel.

But I do not see how you create a "Basement tunnel" because it only lets you drill out your entrances as far as there is a foundation correlating above it. Would you be able to clarify this?

For sure, I can answer both your questions.

Firstly, with the ice lakes - yes that's a known issue, there are several terrain elements that clip into the basement which prevents boxes from being placed. Normally the plugin detects these terrain elements and prevents you from building a basement, but the detection has a bug for ice lakes.

For the tunnels.. in order to build a tunnel you are correct that you will need to set Destroy Basement Cell When Surface Foundation is Destroyed to "false". Once set to false, you will then have to build a bridge of foundations so that you can build a tunnel underneath it. Once you have your basement tunnel you can remove the surface foundations and then you will have your tunnel. Yes, it is very expensive/impractical to do on a vanilla survival server, but that is what the basement building rules allow for.

Hope that helps.

It does help! I was messing with this and figured that out as well!   

With the ice lakes, do you think there's a work around for it? or perhaps in the works. it seems awesome!
