Plugin no longer works after starting new world

[workermaster]

Describe the bug
I installed the plugin and started testing it in an existing map. It worked fine and I decided to start a new map. I replaced the savefile and now the plugin no longer does anything. During my testing, I did get the feeling that the "Lazy tax" option did not work. Setting it to a different value, did not change the ticketprice. I also noticed that when I clicked on the manual refresh, then the price would be a lot lower, before changing again to a much higher numer at the start of the new day.

The dedicated OpenRCT2 server runs as a Docker container on Unraid.

To Reproduce
Steps to reproduce the behavior:

1. Run a dedicated server
2. Install the plugin
3. Reboot the server
4. Check that the plugin works. I checked it by clicking the button to make all rides free.
5. Shutdown server
6. Replace savefile with the world that you want to play
7. Reboot the server
8. Open the map that you just replaced
9. The plugin no longer does anything

Expected behavior
I exepected the plugin to work on any savefile that I load in the server.

Screenshots
I can make screenshots if needed, but am not sure if a screenshot of the plugin helps here, since the buttons do not work.

Desktop (please complete the following information):

• OS: Unraid 6.9.2
• Docker container https://hub.docker.com/r/ich777/openrct2server/
• OpenRCT version 0.4.0

Additional context
I am not great at debugging things, so please tell me what you need and where I can find it.
