Saves aren’t compatible unless specified otherwise.
Thank you for answer 
There are some changes in the works that will hopefully mean saves will work across versions, but for now they’re unfortunately broken any time a new item or tile is added.

This bug was my fault (the construction one). Sorry about that. Fixed and opened a pull request.
Will merge as soon as I get to a computer with a real browser.
I assume by ‘fixed the construction menu’ you mean the broken scrolling?
Also have a title.
Yeah, the scrolling.
