[TOGoS][0.17.1] Map preview, random seed stops working after importing exchange string

[Pinga]

When creating a new game the "random seed" button stops working after you import a map exchange string.

Steps to reproduce:
- Play / New Game
- Expand Preview
- Import map exchange string (input a string then confirm)
- Click "Random seed"
- The number of the seed will change, but the map itself won't update

Id like to confirm this issue, kinda annoying because I like to set up my settings properly via reloading the preview pane several times. When I found a preset I like I save the map exchange string to be able to come back and generate a new seed and hit play. However, I noticed this bug and was stuck with the seed that was contained within the map exchange string.

The work around I found was to just start the map and then hit restart from within the menus. Or alternatively, quit the game and start a new map, since the settings are remembered.

Can confirm with .4

Can confirm this is still the case with 0.17.7

However, it will start working again IF you change the default/railworld/etc dropdown to something else from the default "default".

This is however slightly annoying when you are using custom settings.

Should be fixed for 0.17.9. Thanks for the report!
