Hey it seem that when a worm breach an enriched uranium wall it hard crash the game.
I have tested it in editor with only space age and the mod.

You can repro it if you put the big worm of vulcanus and some enriched uranium wall.

The others dont have problem, maybe is the mirrored damage that dont work well.

Thanks for the fix :)

I tried this and this is a bug in the game. As soon as the wall deals damage to the Demolisher, it crashes. However, the Demolisher is only on Vulcanus, so just don't build these walls there.
The bug has been reported, so hopefully it will be fixed in a future update.

I currently don't know how to add an exception to ignore a specific entity :-/

Edit: This should be fixed in the next release of the game.

Yeah it seems thanks for the response :).
Kudos to the dev for fixing it :)

Fixed in 2.0.24 ;-)
