Thank you for reporting this bug. I have now fixed the Shelter Wave Defense panel.
The panel now has a working expand/collapse button:
- Click the
− button to collapse the large panel into a compact single-line summary.
- When collapsed, the button changes to
+.
- Click the
+ button to expand the panel and view all information again, including the timer, next-wave estimate, active enemies, spawn queue, tunnels, and Boss status.
This allows each player to keep the full information visible when needed or collapse it to save screen space. In Shelter Defense, the panel now also correctly displays “Shelter Wave Defense” instead of “Train Wave Defense.”
Please make sure that the correct game mode is selected under Settings > Mod Settings > Startup before loading your save. Train Interiors and Shelter Defense are mutually exclusive:
- If Shelter Defense is selected, Train Interiors and its Train Wave Defense panel will not operate.
- If Train Interiors is selected, Shelter Defense will not operate.
This is intentional, as only one of these two game modes can be active at a time. The selected game mode should always match the type of save you are loading.
Thank you again for finding and reporting the issue. If you notice any other bugs or unexpected behaviour, please feel free to open another report.
