when the dredgeworks mod is installed, this mod tries to spawn a generic biter resource nest on submerged resources. This is stable up until it activates and realizes it doesn't know what projectile to shoot at you, resulting in a crash.

The mod Biter Resource Nests (1.0.4) caused a non-recoverable error.
Please report this error to the mod author.

also while we're here: maybe a mod option to turn of nest projectiles altogether? You don't have to but I think it would be neat.

Interesting. It's supposed to default to a generic nest when it encounters a non standard resource. It might be a problem with having no targatable land when trying to choose a projectile location.
I'm currently working on moving the custom projectiles to worm enemies, which should work a lot better. If I can I'll add a toggle at world gen to let people disable worms or not.

Fun. Out of curiosity, how are you planning to manage worm disposal? worms don't really spawn biters after all so I wonder how you measure when they go dormant.

I'll keep the nests as they are, i'll just make them spawn the worms to handle shooting the projectiles. I should probably also make nests not be able to spawn in water, as the biters cant swim.

Yes please, I'm playing with There Be Biters, and I'm kinda tired of not being able to build on the south side of my starting area without a crash.

Okay, I added a map setting to let you toggle the projectiles from the nests. You should be able to turn them back on after you build your way out of the starting moat. Let me know if its still crashing

thanks! I'll go test it out.
