Hello, this mod made me laugh but as far as I understand for unlocking certain techs you need to catch a specific biter, in my case I'm stuck at lowest tier as thay are simply does not spawn anymore. Would that be more friendly to simply change research costs to good-old science packs so people who downloaded your mod for their existing factories could start it?

Hello! That's a valid point. I will make it if you catch a biter you will unlock that tier's tech, as well as any previous tiers that's not already unlocked.

That is also cool approach, thank you for your response, waiting for it patiently!

This should be fixed in the latest release. Thanks for the report!
