Disclaimers

• I have searched the issue tracker to check if the issue has already been reported.
• My issue happened while using mods.

What happened?

as the title implies, some incomplete level generation leads to an alien ruin being generated without enough scan targets for me to complete the Scan Alien Ruin mission (2 targets instead of 3). I did not check the issue tracker as I am 95% shure that this is a seed specific problem.

Reproduction steps

seed error, may help to have an alien ruin mission
bokensave.zip
if the attached save works then it should have the issue
If image attachment works then it should be a screenshot of the terminal with the error and showseed command.
