Just an update here. I have investigated this, reproduced your first issue, and fixed it.
However, I have not built this project for about a month and its dependencies have had hundreds, if not thousands, of changes in that time. I'm working through a lot of other issues caused by upstream dependencies and need to get through a successful QA phase before I can actually push a new build up. I'm hoping to get through it this weekend but I'll post a final update when a new build is up.
The other two issues are a little too vague to reproduce and fix. However, there may be a file called either "error.log" in your AppData/Roaming/terrascriber directory. If you're willing to email that to games at narfox.com I will see if it helps me diagnose the other issues.
